Interesting Xenon Facts and Uses in Chemistry

Although its a rare element, xenon is one of the noble gases you may encounter in daily life. Here are some interesting facts about this element: Xenon is a colorless, odorless, heavy noble gas. It is element 54 with the symbol Xe and an atomic weight of 131.293. A liter of xenon gas weighs more than 5.8 grams. It is 4.5 times denser than air. It has a melting point of  161.40 degrees Kelvin ​(−111.75 degrees Celsius, ​−169.15 degrees Fahrenheit) and a boiling point of  165.051 degrees Kelvin ​(−108.099 degrees Celsius, ​−162.578 degrees Fahrenheit). Like nitrogen, its possible to observe the solid, liquid, and gas phases of the element at ordinary pressure.Xenon was discovered in 1898 by  William Ramsay and Morris Travers. Earlier, Ramsay and Travers discovered the other noble gases krypton and neon. They discovered all three gases by examining components of liquid air. Ramsay received the 1904 Nobel Prize in Chemistry for his contribution to discovering neon, argon, krypton, and xenon and describing the characteristics of the noble gas element group.The name xenon com es from the Greek words xenon, which means stranger, and xenos, which means strange or foreign. Ramsay proposed the element name, describing xenon as a stranger in a sample of liquefied air. The sample contained the known element argon. Xenon was isolated using fractionation and verified as a new element from its spectral signature.Xenon arc discharge lamps are used in the extremely bright headlamps of expensive cars and to illuminate large objects (e.g., rockets) for night viewing. Many of the xenon headlights sold online are fakes: incandescent lamps wrapped with a blue film, possibly containing xenon gas but incapable of producing the bright light of genuine arc lamps.Although the noble gases generally are considered inert, xenon actually does form a few chemical compounds with other elements. Examples include xenon hexafluoroplatinate, xenon fluorides, xenon oxyfluorides, and xenon oxides. The xenon oxides are highly explosive. The compound  Xe2Sb2F1   is particularly notewo rthy because it contains a Xe-Xe chemical bond, making it an example of a compound containing the longest element-element bond known to science.Xenon is obtained by extracting it from liquefied air. The gas is rare but present in the atmosphere at a concentration of about 1 part per 11.5 million (0.087 parts per million.) The gas is present in the Martian atmosphere at approximately the same concentration. Xenon is found in the Earths crust, in gases from certain mineral springs, and elsewhere in the solar system, including the sun, Jupiter, and meteorites.It is possible to make solid xenon by exerting high pressure on the element (hundreds of kilobars.) The metallic solid state of xenon is sky blue. Ionized xenon gas is blue-violet, while the usual gas and liquid are colorless.One of xenons uses is for ion drive propulsion.  NASAs Xenon Ion Drive engine fires a small number of xenon ions at high speed (146,000 km/hour for the Deep Space 1 probe). The drive may propel spacecraft o n deep space missions.Natural xenon is a mixture of nine isotopes, although 36 or more isotopes are known. Of the natural isotopes, eight are stable, which makes xenon the only element except for tin with more than seven stable natural isotopes. The most stable of xenons radioisotopes has a half-life of  2.11 sextillion years. Many of the radioisotopes are produced via the fission of uranium and plutonium.The radioactive isotope xenon-135 may be obtained by beta decay of iodine-135, which is formed by nuclear fission. Xenon-135 is used to absorb neutrons in nuclear reactors.In addition to headlamps and ion drive engines, xenon is used for photographic flash lamps, bactericidal lamps (because it produces ultraviolet light), various lasers, moderate nuclear reactions, and motion picture projectors. Xenon can also be used as a general anesthetic gas.

Racial Profiling And The United States - 1160 Words

African-Americans are the primary race being treated poorly. Throughout history, African Americans have gone through many hardships with being slaves and although slavery was abolished African Americans were still not granted their full freedom and they continued to be segregated from other races. African Americans hold many negative stereotypes most of which are not true. Due to these negative stereotypes, African Americans are most likely to be targeted by police and many other people for committing crimes.
