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
A chemical symbol is an abbreviation of the name of a chemical element. The name is derived from the name of the element, which is usually in Latin. Chemical symbols are made up of one or two letters.Full Answer >
The chemical element, nitrogen, was formally named by the French chemist Jean-Antoine Claude Chaptal when he discovered that it is a primary component of potassium nitrate, also known as nitre. The name of nitrogen is derived from the combination of the two Greek words "nitron" and "genes," meaning niter forming.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 >
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 >
