10 Neon Facts †Chemical Element

10 Neon Facts - Chemical Element Neon is element number 10 on the periodic table, with the element symbol Ne. While you might think of neon lights when you hear this element name, there are many other interesting properties and uses for this gas. Here are 10 neon facts: Each neon atom has 10 protons. There are three stable isotopes of the element, with atoms having 10 neutrons (neon-20), 11 neutrons (neon-21), and 12 neutrons (neon-22). Because it has a stable octet for its outer electron shell, neon atoms have 10 electrons and no net electrical charge. The first two valence electrons are in the s shell, while the other eight electrons are in the p shell. The element is in group 18 of the periodic table, making it the first noble gas with a full octet (helium is lighter and stable with only 2 electrons). Its the second lightest noble gas.At room temperature and pressure, neon is an odorless, colorless, diamagnetic gas. It belongs to the noble gas element group and shares the property with other elements of that group of being nearly inert (not very reactive). In fact, there are no known stable  neon compounds, even though some other noble gases have been found to form chemical bonds. A possible exception is solid neon clathrate hydrate, which may be formed from neon gas and water ice at pressure of 0.35-0.48 GPa. The name of the element comes from the Greek word novum or neos, which means new. British chemists Sir William  Ramsay and Morris W. Travers discovered the element in 1898. Neon was discovered in a sample of liquid air. The gases that escaped were identified as nitrogen, oxygen, argon, and krypton. When the krypton was gone, the remaining gas was found to emit a bright red light when ionized. Ramsays son suggested the name for the new element, neon.Neon is both rare and abundant, depending where youre looking for it. Although neon is a rare gas in the Earths atmosphere (about 0.0018% by mass), it is the 5th most abundant element in the universe  (1 part per 750), where it is produced during the alpha process in stars. The sole source of neon is from extraction from liquefied air. Neon is also found in diamonds and some volcanic vents. Because neon is rare in air, its an expensive gas to produce, about 55 times more expensive than liquid helium.Even though its rare and expensive o n Earth, there is a fair amount of neon in the average home. If you could extract all the neon from a new home in the United States, you have about 10 liters of the gas! Neon is a monatomic gas, so it is lighter (less dense) than air, which consists mostly of nitrogen (N2). If a balloon is filled with neon, it will rise. However, this will occur at a much slower rate than you would see with a helium balloon. As with helium, inhaling neon gas poses an asphyxiation risk if not enough oxygen is available to breathe.Neon has many uses besides lighted signs. It is also used in helium-neon lasers, masers,  vacuum tubes, lightning arresters, and high-voltage indicators. The liquid form of the element is a cryogenic refrigerant. Neon is 40 times more effective as a refrigerant than liquid helium and 3 times better than liquid hydrogen. Because of its high refrigeration capacity, liquid neon is used in cryonics, to freeze corpses for preservation or for potential revival in the future. The liquid can cause immediate frostbite to exposed skin or mucous membranes.When low pressure neon gas is electrified, it glows reddish orange. This is the true color of neo n lights. Other colors of lights are produced by coating the interior of the glass with phosphors. Other gases glow when excited. These are not neon signs even though many people commonly assume they are. One of the more interesting facts about neon is the light emitted from ionized neon can pass through water fog. This is why neon lighting is used in cold regions and for aircraft and airports.Neon has a melting point of  Ã¢â‚¬â€˜248.59  Ã‚ °C (‑415.46  Ã‚ °F) and boiling point of  Ã¢â‚¬â€˜246.08  Ã‚ °C (‑410.94  Ã‚ °F). Solid neon forms a crystal with a close-packed cubic structure. Because of its stable octet, the electronegativity and electron affinity of neon approaches zero.

Free Essays on Integration Of Asian Culture

The integration of Asian culture into American society has, by and large, been highly successful. Through diligence and perseverance Asian Americans have lived up to the title of â€Å"model minority†. The Asian community has earned a great deal of respect in regards to their high educational drive, significant economic achievement, and a strong sense of nuclear family. However, in a broad sense, the Asian American community, even with such a reputation, lacks a cohesive force to bring each ethnicity together. With all our motivation and progress, there still remains tantamount the need for a voice; the desperate cry for unity in our community. There is a saying among the youth: â€Å"Asians need to stick together†. But, more often than not, there remains the shadow of ethnocentrism separating our vast cultures, breaking down any efforts to organize a formidable force in American society. This is a serious problem that affects Asians worldwide and needs to be add ressed immediately starting with the youth. It is in these young people that seeds of unity and cultural bonding can be planted to create the leaders of tomorrow. The day will come when future leaders will carry the community into a new era, but a foundation must be laid out before the building is erected. We begin with a single brick: awareness. It is quite ironic that though Asian Americans tend to have strong bonds between immediate family members and much loyalty towards their individual cultures, there seems to be an air of arrogance and feelings of superiority against other Asian cultures. Perhaps the very same ambitious, competitive nature that many Asian Americans share serves to create this hostility, perpetuating inter-cultural prejudice. Many young Asian Americans know first-hand that their immigrant parents may tend to be very stubborn and reluctant to release themselves from these self-defeating beliefs. It is that same doggedness that was essential for...

Analysis of the music video Destiny's Child - Cater 2 U Essay

Analysis of the music video Destiny's Child - Cater 2 U - Essay Example The song, Cater 2 U, has a general gendered meaning; that men will enjoy the rewards of love and compassion following a point where their female lovers notice that they are working hard. The music video casts feminine figures whose romantic actions could create an impression to the hard working man. In addition, it acts as a clear depiction of the level to which a hardworking man inspires his female companion (Sfetcu 16). When a woman notices the hardworking nature of her male lover, she will gain inspiration to make such a man happy and thus, want to accommodate him in a great way. In this perspective, a woman's submission to a man would be best when the man deserves it and thus, gives it back; a hardworking man furnishes her woman and gets back all the lovely accommodation. Form The text's enhanced application of formal techniques allows it to reinforce the overall meaning. The music video's shooting took place at a desert, which depicts a decision by the trio to go natural, which makes the video more authentic. The desert scenery, as well as the exquisiteness of the trio mainly enhances the clip. However, the presence of male actors seems to be superfluous to the music video's scene of female pleasures and bodies. However, the enriching nature of the feminine shooting acts as a balancing factor, which helps in driving the theme that the male actors depict to the audience. The natural lighting of the music video's shooting period helps in showing the natural feminine look of the females in the music video.
