Krypton (Kr)

Krypton is the 36th element in the periodic table and has a symbol of Kr and atomic number of 36. It has an atomic weight of 83.798 and a mass number of 84. Krypton has thirty-six protons and forty-eight neutrons in its nucleus, and thirty-six electrons in four shells. It is located in group eighteen, period four and block p of the periodic table. Colorless gaseous element, belongs to the noble gases. Occurs in the air, 0.0001% by volume. It can be extracted from liquid air by fractional distillation. Generally not isolated, but used with other inert gases in fluorescent lamps. Five natural isotopes, and five radioactive isotopes. Kr-85, the most stable radioactive isotope, has a half-life of 10.76 years and is produced in fission reactors. Practically inert, though known to form compounds with Fluorine.

History

Scottish chemist Sir William Ramsay and his assistant English chemist Morris Travers discovered krypton in 1898 in London. They found krypton in the residue left from evaporating nearly all components of liquid air. William Ramsay was awarded the 1904 Nobel Prize in Chemistry for discovery of a series of noble gases, including krypton. From the Greek word kryptos, hidden

Discoverers	Sir William Ramsey, M.W. Travers
Discovery Location	Great Britain
Discovery Year	1898
Etymology (Name Origin)	Greek: kryptos (hidden).
Pronunciation	KRIP-ton (English)

Krypton is considered to be non-toxic

When ionized, krypton gas emits bright white light

Uses

Krypton is used in certain photographic flash lamps for high-speed photography. Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways. Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs. Used in lighting products. Some is used as inert filler-gas in incandescent bulbs. Some is mixed with argon in fluorescent lamps. The most important use is in flashing stroboscopic lamps that outline airport runways.

Sources

Forms 1 millionth of the atmosphere. Obtained from production of liquid air.
