Krypton is a chemical element that can be found in trace amounts in the atmosphere. It is a colorless, odorless and tasteless noble gas that can be isolated by fractionally distilling liquefied air.Know More
Krypton is most commonly used in combination with other rare gases in fluorescent lights, and it can be used in photography. This element gets its name from the Greek word "kryptos," which means "hidden." Krypton was discovered by Sir William Ramsay in 1898 while he was studying liquefied air. He noticed that small amounts of liquid krypton remained after the most combustible components of the liquid air had boiled away. Through further observations and calculations, he deduced that the Earth's atmosphere is only about .0001 percent krypton.
Krypton can be used with other gases to make signs that glow with a green and yellow light. It also has a large number of spectral lines, which makes it play an important role in the formation and production of high-powered gas lasers. Krypton is one of the products of uranium fission, and when krypton has been solidified, it takes on a white and crystalline appearance that features a cube-crystal face. This face is a common feature in all of the noble gases.Learn More
Nitrogen is important to life because it comprises approximately 80 percent of the Earth's atmosphere and is present in all living things as a part of proteins and DNA, according to the Marine Biological Laboratory. Nitrogen is present in the amino acids that make up proteins. It is also essential to reproduction because it is present in the nucleic acids in genetic material, or DNA.Full Answer >
Argon is an inert gas found in the Earth's atmosphere. It is the fourth most common gas in the air, behind oxygen, carbon dioxide and nitrogen. It has an atomic number of 18 and uses the atomic symbol, Ar, according to About.com.Full Answer >
Oxygen is one of the primary components that allows air to be breathable to people and it began forming in the atmosphere approximately one billion years ago. Until the ozone layer formed, most life on the planet was restricted to the oceans.Full Answer >
Other than its place on the periodic table of the elements with the other noble gases, the main source of neon on Earth is in the atmosphere. This element is very rare on Earth, though it is one of the four most commonly occurring elements in the universe. Earth just happens to have a very low concentration of neon relative to other parts of the universe.Full Answer >
