Atomic Number 13 - Interesting Aluminum Facts

Aluminum (aluminium) is the element that is atomic number 13 on the periodic table. Its element symbol is Al and its atomic mass is 26.98. Each atom of aluminum contains 18 protons. Aluminum atoms with fewer than 18 electrons are cations, while those with more than 18 electrons are anions. The isotope of aluminum is determined by its number of neutrons. Here is a collection of interesting facts about atomic number 13. Element Atomic Number 13 Facts Pure aluminum is a soft, nonmagnetic silvery-white metal. Most people are familiar with the pure elements appearance from aluminum foil or cans. Unlike many other metals, aluminum is not very ductile, which means it isnt readily drawn into wires. Aluminum is strong, yet light  compared with most other metals.Aluminum is the third most abundant element in the Earths crust  (about 8%) and the most abundant metal.Aluminum ore (bauxite) is mined, chemically refined into alumina (aluminum oxide) using the Bayer process, and finally refined into aluminum metal using the electrolytic Hall-Heroult process. The modern process requires considerable energy, yet its much easier than past refining methods. It was so difficult to obtain element 13 that is was considered a precious metal. Napoleon III served dinners to his most important guests on aluminum platters, leaving lesser guests to dine using gold!In 1884, the cap of the Washington Monument was made using aluminum because the metal was so highly valued at that time.Only 5% of the energy needed to purify aluminum from alumina is required to recycle aluminum from scrap. In fact, you can even recycle the element at home, if you like.The name for element 13 has been either aluminum or aluminium. We can blame the English chemist, Sir Humphy Davy, for the confusion. Davy initially called the element alumium in 1807, from the mineral alumina. Davy changed the name to aluminum and then finally to aluminium in 1812. The -um spelling persisted in Britain for a while, eventually changing to aluminium. Chemists in the United States actually used the -ium ending, shifting toward the -um ending in the 1900s. In the 1990s, the International Union of Pure and Applied Chemistry formally determined element 13 should be aluminium, yet the -um spelling persists in the U.S. Its worth noting that despite the naming controversy he caused, Davy neither discovered the element nor isolated it!Although aluminum is present in over 270 miner als and is widely abundant, the element does not appear to serve a biological role in either animals or plants. The presence of aluminum salts is generally tolerated by animals and plants. However, in high doses aluminum exposure alters the function of the blood-brain barrier. Some people are allergic to aluminum. Ingesting acidic foods increases aluminum absorption, while the flavor enhancer maltol increases its accumulation in bones and nerves. Aluminum increases estrogen-related gene expression in breast cells of humans. The US Department of Health and Human Services classifies aluminum as a non-carcinogen. Whether or not aluminum is a factor in Alzheimers disease is a matter of debate. It is unknown whether aluminum contributes to the degenerative disease or whether developing the disease results in accumulation of the element.Element atomic number 13 conducts electricity, although not as well as silver, copper, or gold. If you have metal dental fillings or braces, you can exper ience this firsthand. When you bite on a piece of aluminum foil, the salts in saliva conduct electricity between the foil and the filling, creating a type of galvanic battery and delivering an electrical shock to your mouth.Uses of aluminum are second only to those of iron and its alloys. While nearly pure aluminum may be used, the element is also alloys with copper, zinc, magnesium, manganese, and silicon. The pure element is used when corrosion resistance is paramount. Alloys are used where strength or hardness are important. Aluminum is used in beverage containers because of its corrosion resistance. The metal is used in construction, transportation, and to make everyday household items. High-purity aluminum is used in wires, electronics, and CDs. The metal is used to make reflective surfaces and paint. Some string instruments, especially guitars, have aluminum bodies. Aircraft bodies are made of aluminum alloyed with magnesium.

The Impact Of Television On The World Of The 20th Century...

One of the most successful inventions of the 20th Century is the Television. Many describe Television as a way to connect with the wider world, with some even going as far as to use the device to escape from everyday life for an hour or two. Now, thanks to increasing technological developments, this escape can be made considerably easier with the introduction of mobile TV- the use of Smartphones, tablets, and arguably most prominently, computers and laptops, bringing with it the expansion of online Television services such as Netflix. The reason for exceptional developments in Television can be based off of the large growth in technology, and thus has led to an increased demand from its viewers. Despite the immense popularity with computer gaming and the Internet, Television still remains the most popular medium in New Zealand. However, before the likes of Netflix, there were no online providers. TV consumers outnumbered online users for years after the initial developments, as content was better on a Television rather than online due to the lack of variety and services available digitally over the Internet. Consumers watched Television for the escape from reality for an hour or two, and this was unavailable on a computer as there were no websites or Networks offering the content users wanted. A Nielsen study in 2012 on the media devices owned by people showed that 290 Million Americans (or around 92%) owned at least one Television, compared to 192 Million Americans thatShow MoreRelatedThe Evolution of Media Essay 1312 Words   |  6 Pagessignificantly.

A Valiant Voice free essay sample

Someone is tugging at my shoulders impatiently. I slowly open my eyes, squinting into the unfamiliar brightness of the airplane cabin, the foreign, motionless faces around me, and the velvety darkness outside my window. A young, resonant voice comes over the loudspeaker, but I can barely understand her. I glance at my mother’s weary, expectant face and happen to catch the arrows on her watch forming 4 a.m. Omsk’s current time. I cry. I want to go back to sleep and soothe my tired body. A pleasant young man, also Russian, evidently seeing my distress, comforts me from his seat, â€Å"Don’t cry, devochka. You’re in America.† That was February 4, 1999. Sometimes I close my eyes and think about that endless journey from eastern Russia across the Atlantic, recollecting the details: my wooly shooba and valenki, my mother’s anxious smile, the two Russian-English dictionaries my father kept in each of his pants pockets, and the endless chatter that I could not yet understand. We will write a custom essay sample on A Valiant Voice or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page My memories, though a little faded, help me to recognize how I have changed from that quiet girl of nine to an outspoken American young adult. I look back at the dreams and goals of my past and the hurdles I have overcome, trying to evaluate how far I have come and how much further I can still go. One week after my arrival, my footsteps marked the floors of Anne Frank Elementary for the first time. With shaky knees and sweaty palms, I took my first step toward assimilation. I would almost surrender to the myriad hindrances in my way: my peers’ mockery of my quiet, broken English; my strain to excel in ESL class; and the anguish I felt when I found out that the only other Russian girl in my class, my only guide and translator, deliberately mistranslated my words to others and theirs to me. I spent every free minute tackling grammar or vocabulary, desperately wanting to learn English quickly. I dreamed of the day when my voice would be heard and understood. Two years after arriving in America, I stood in front of 300 students and teachers, and heard the clear sound of my voice spelling sixth-grade vocabulary words at a traditional American spelling bee. Amid the jubilant clamor of kids, the zipping of backpacks and the crinkling of papers one Friday afternoon, my teacher had pulled me aside, asking me to represent my class in the annual spelling bee. That day, as I rode the school bus home, I impatiently counted down the streets to my stop, anticipating my mother’s warm smile when I told her the news. I made myself promise to study 15 words every morning so that when the competition was finally at hand, no anxious thoughts would hinder my performance. Every day for the next three weeks, I woke up an hour early to study before school. I didn’t win the 2001 spelling bee championship, but this seemingly small step gave me courage. From then on, with every small hurdle overcome, the negativity of those around me faded and my b elief in myself grew substantially. Last summer, this time without apprehension, as the student coordinator of Team Myanmar in the International Communications and Negotiations Simulation, I began each meeting with poise and confidence. Conveying my opinions and letting my voice glide boldly and smoothly seemed natural. Less than eight years later, I can say that the shy little girl who first stepped off the plane into an unfamiliar world has vanished. In her place stands a young woman who conquers mountains with a calm smile and a resolute stride.

The Lamb by William Blake Summary and Analysis Example For Students

The Lamb by William Blake Summary and Analysis The speaker, identifying himself as a child, asks a series of questions of a little lamb, and then answers the questions for the lamb. He asks if the lamb knows who made it, who provides it food to eat, or who gives it warm wool and a pleasant voice. The speaker then tells the lamb that the one who made it is also called the Lamb and is the creator of both the lamb and the speaker. He goes on to explain that this Creator s meek and mild, and Himself became a little child. The speaker finishes by blessing the lamb in Gods name. Analysis William Flakes The Lamb is an intricately complex poem written in 1789. The poem takes its central focus the grand question of creation, but it does so in an understated way, opening as a simple question to a sweet, delicate creature: Little Lamb, who made thee? The first half of the two-stanza poem has the speaker ask the lamb who is responsible for life and creation of this sweet creature with the softest looting of delight and Gave thee such a tender voice. The lamb functions as a symbol for the connection between humanity and the natural world. We will write a custom essay on The Lamb by William Blake Summary and Analysis specifically for you for only $16.38 $13.9/page Order now Associated with the rural English countryside, the lamb is also a symbol of pastoral innocence, bridging the gap between the urban world of humanity and the natural world of Gods creation. Pastoral life also takes a central position in the poem. The collection of work in which this poem appears, Songs of Innocence, includes many Astoria scenes. These idyllic images of life outside of bustling cities firmly establishes a sense of peace and tranquility within these poems, including the The Lamb. This connects the figures of the poem to the natural world, where the figures of the poem can contemplate their existence without the interference of completely human elements. Flakes gentle phrasing lends a reflective, spiritual mood to the piece, which answers the question in first-person narrative in the second stanza that higher power is responsible. In answering as Jesus Christ, Blake displays his own reverence for God in the phrases: He is called by thy name, For He calls Himself a Lamb. He is meek, and He is mild; He became a little child. I a child, and thou a lamb, We are called by His name. Little Lamb, God bless thee! Little Lamb, God bless thee! By stating the lambs creator as Jesus Christ, Blake is establishing that everyone is in some sense a little lamb, created by God.

Fiat cultural clash Essays

Fiat cultural clash Essays Fiat cultural clash Essay Fiat cultural clash Essay FIAT (Fabrica Italiana Automobili Torino), was established by the Italian government in 1899, and in 1907 was bought by Giovanni Agnelli. Fiat is an automobile manufacturer, engine manufacturer, financial and industrial group based in Turin, in the Piedmont region. The company flourished under Agnellis leadership, in large part due to his innovative ideas concerning the structure of production as well as his experience in mass marketing strategies, particularly in foreign sales. After the World War II, in March 1945, the local court of the national liberation committee Comitato di Liberazione Nazionale accused Agnelli of collaboration with the Nazis and removed him from the firm. He died seven months later. It was a family owned business until September 2010 when shareholders approved a plan to split Fiats industrial business from the group. Fiat operates in 61 countries with 1,063 companies that employ 223,000 people, 111,000 of whom are outside Italy. As of 2009, Fiat is the worlds 9th largest carmaker. In order to keep that place and even grow Fiat needs to become part of the fastest growing market in the World, China. The Italian carmaker wants not only to manufacture his cars in China, but also to sell them to the Chinese. Forming a joint-venture company seemed to be the quickest and most effective way of developing good quality relations in a country such as China. Fiat made an attempt to introduce in China with a joint-venture with a local firm: Nanjing. : Unfortunately, the joint-venture failed. The aim of this assignment is to analyze the cultural reasons and differences in Fiats joint ventures and to analyse what are the cultural reasons for the failure of this business. Corporate culture- Every human society has its own shape, its own purposes, its own meanings. (Williams, 1958). Culture is the whole way of life of a people. Culture seves as a lens through which we perceive the other. Corporate culture is something that managers have to establish and run all the way through a business, with clear values and beliefs, successful business principles and operations, and a suitable emphasis on human resources and customer satisfaction. Fiats corporate culture will be strongly influenced by the Italian culture. According to Huntington: A civilization is a cultural entity. European communities will share cultural features that distinguish them from Arab or Chinese communities. Arabs, Chinese and Westerns, however, are not part of any other broader cultural entity. They constitute civilizations. Therefore Fiats culture will be influenced not only by the Italian, but also by the European culture, too. Before embarking on any important business projects, Italians feel the need to really know the people; they are going to do business with on a personnel level. According to Fung (1998), Chinese customs, religion, and health practices are rich and complex and have stood the test of time over many millennia. China has one of the four oldest civilizations in the world and a written history of 4,000 years. The Chinese are very proud of their culture and history. They value their own culture and religion, but they are open and pragmatic toward the religion and cultures of others. Chinese people in general are peaceful, hard-working, and easily contented. They follow norms of social order. For example, they respect authority figures and elders, and they are patient with their peers. The Chinese value modesty, reserved behaviour, and humility. They believe in harmony and tend to avoid confrontation. They will, however, push and sacrifice for their children. The roles of members of a Chinese family are highly interdependent ( Ong, 1993). Traditionally, the family has been the most fundamental and important unit of society among the Chinese, and this is still true. The family is also an important economic unit. In todays China, it is still very common for three generations to live under one roof. C. Lam (1992) noted that Confucian philosophy advocates the virtue of sacrificing individual needs for the good of the group.

Roosevelt Essay Example | Topics and Well Written Essays - 750 words

Roosevelt - Essay Example But it is more likely that the paternalistic notions of the Roosevelt conservationists included a belief that somehow the federal government could enact a balance between traditional and modern America. In this sense conservation legislation was intended to preserve the status of representatives of older America by insuring that they could adapt to the new times (Morris 234). Thus the Newlands Act, which protected the small homemaker from monopoly and oppression by the intrusion of a benevolent government into local affairs, clearly envisaged a society where each man could develop expertise without losing his identity or trampling upon someone else. Since industrialism, with its rapid technological changes and consequent social flux, threatened the maintenance of balanced progress, an enlightened government of experts was needed to insure that modern America somewhat resembled the nation from which it had sprung. Roosevelt received a reputation as a "trust builder". ... Roosevelt spoke of the "square deal" in domestic affairs and of "gentleman's agreements" in foreign policy. This morality in government was perfectly consistent with a consensus of values which affirmed equality of opportunity, the right of the common man, and the democratic political process, while at the same time upholding an open-class society with acknowledged leaders, correct practices, and certain social barriers. In reorganizing the structure of the government, the technocratic paternalists were attempting to insure the "stability of American institutions" in what they recognized as a changing age. In appealing to traditionalist patterns of behavior, such as self-reliance, and eulogizing traditional success models, such as the yeoman farmer, they were articulating America's need to reassert the common elements of her heritage. More moral functions they could not have imagined (Morris 296). The Roosevelt administrators may have recognized that one logical extension of rapid in dustrialization was a new American ethos built upon science and technology, fully urbanized, symbolized by large corporate structures, and ruled by an educated elite, but they were less capable of recognizing that this ethos was far removed from the rural, individualistic, agrarian, egalitarian one of their fathers. As President Coolidge stressed repeatedly, the great American need is not more law enforcement but better general law observance. A square deal involves a just tax system, really a system for nation, state and locality combined; one that is fair as a whole not simply just in spots. The giving of a square deal is an inescapable responsibility of a democratic society. To secure it we shall need the best

The strategies( taxation) used to reduce tobacco related harms Essay

The strategies( taxation) used to reduce tobacco related harms - Essay Example The rationale for increased taxation of tobacco products is that higher taxes will translate into high prices for tobacco products. Proponents of this strategy opine that when tobacco products have higher prices, the demand is likely to decrease. Many countries have implemented this strategy as one of the efforts of addressing increase tobacco consumption (Cowie, Glover, & Gentles, 2014). Worth noting is the fact that tobacco consumption contributes to a remarkable percentage of deaths. For this reason, it is important to evaluate the efficiency of the taxation strategy for reducing tobacco consumption. This paper will evaluate the efficiency of the taxation strategies on tobacco consumption, relying on evidence-based research. There is evidence that taxation strategies do not contribute to a significant reduction of tobacco smoking, as this paper will highlight. As highlighted above, the rationale for increasing taxation on tobacco products is based on the fact that tobacco consumption is proving to be one of the most critical public health threats in the twenty-first century. According to future projections, the globe will register 1.6 billion smokers if effective strategies for reducing smoking are not implemented. Many countries have recognized the tobacco epidemic and are putting in measures in an effort to reduce the prevalence of tobacco consumption (Gigliotti, Figueiredo, Madruga, Marques, Pinsky, Caetano, & Laranjeira, 2014). As mentioned previously, increasing tobacco taxes is viewed as one of the best strategies that can register positive results in reducing the prevalence of tobacco consumption. The World Bank has supported the initiative of introducing increased taxes on tobacco products. Proponents of this strategy believe that it can register positive outcomes in various populations. Governments that have implemented this stra tegy also achieve associated revenue goals through
