Krypton-81 and krypton-85 are radioactive isotopes of krypton but have considerably long half-lives. There are around thirty artificial isotopes of krypton. Krypton-84 is the most abundant isotope, 57%. These include krypton-78, krypton-80, krypton-82, krypton-83, krypton-84, krypton-84, krypton-86. There are six stable isotopes in the naturally occurring krypton. There are 25 isotopes of krypton, with mass number ranging from 71 to 95. This can lead to breathing difficulty and lead to drowsiness and unconsciousness. If inhaled in high concentrations, it can act as an asphyxiant and displace the normal concentration of oxygen in the lungs. The international unit of meter in System International use the wavelength of light emitted by krypton isotope, 86Kr, to define distance of one meter.Krypton fluoride lasers are also used in research involving nuclear fusion reactions for the generation of energy.Krypton emits a shaper red light and is used for making red lasers used in high power laser shows.Krypton is used in making flash signs like luminous neon light signs, that glow with a distinct green yellow light.Krypton-85 is used a marker for the detection of nuclear weapon production and research facilities.Krypton is used in making high powered gas lasers and krypton fluoride is used in some lasers.Krypton is also used in high-powered flash lamps on airport runways.It is used for making energy-efficient fluorescent lamps.It is used flash lamps for high speed photography. Krypton is widely used in photography.Crystals of krypton hydride can be formed under increased pressure, i.e. It is a crystalline white solid and is stable at low temperature. However, under extreme conditions, it reacts with fluorine and forms krypton difluoride (KrF 2). Krypton is highly volatile and quickly vaporizes when exposed to water. Krypton is affected by an external magnetic field and is diamagnetic. Krypton has a density of 3.749 g/L at standard conditions and is almost three times denser than air. Krypton gives two distinct lines of green and yellow color in its emission spectrum. Krypton in solid state is white and have a cubical structure. Krypton is also produced during the uranium fission reaction.
Krypton is obtained by fractional distillation of liquid air. It is present in about 1ppm in the Earth’s atmosphere. The name krypton has been derived from the Greek word, kryptos, that means “hidden”. And the gap between argon and helium in the periodic table made him look closely within elements. Before its discovery, Ramsay believed that in nature, often element hides in another. Ramsay received the Nobel prize in Chemistry in 1904 for his contributions in the discovery of krypton and other noble gases, except radon. Krypton was discovered by Sir William Ramsay and Morris Travers in 1898, as a residual gas in a chamber after all components of liquid air have been evaporated. It emits unique and sharp spectral lines and is widely used in high speed photography and lasers. It was discovered by Sir William Ramsay in 1898. Krypton is a rare and inert gas and belong to the Nobel gases.
