Krypton-based bulbs serve as excellent white light source for photographic flashes in high speed photography.

High-power, flashing airport runway lights The groundwork for finding krypton was laid in 1785, when Henry Cavendish observed that the air contained a fraction that was neither oxygen nor nitrogen.

Krypton is a member of group 18 (noble gases) elements. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure.

Some of the applications of krypton include the following: Discoverer of Krypton Ramsay, Sir William & Travers, Morris. It is a colorless, odorless, tasteless inert gas.The key properties of krypton are listed below: Krypton can be extracted by subjecting liquefied air to fractional distillation and removing carbon dioxide, nitrogen, water vapor and oxygen from the resulting residues of liquefied air. Of these, six isotopes 78Kr, 80Kr, 82Kr, 83Kr, 84Kr and 86Kr occur naturally. Krypton has 33 known isotopes with mass numbers ranging from 69 to 101.

Before its destruction, it was home to a great civilization which boasted advanced science and technology. Very small amount of krypton can also be formed in the Earth’s crust when uranium or other radioactive elements disintegrate. Krypton is a planet which orbits a red star. Traces of krypton of around 1 ppm are present in the atmosphere. The wealthy industrialist Ludwig Mond gave them a new liquid-air machine and they used it to extract more of the rare gas krypton. They had already extracted neon, argon, and krypton from liquid air, and wondered if it contained other gases. As expected, they found argon gas in addition to two new lines in the spectrum, which was found to be a new element - krypton. Xenon was discovered in July 1898 by William Ramsay and Morris Travers at University College London.

The remaining gas was placed in a vacuum tube to which a high voltage was applied for measuring the gas spectrum. To identify the unknown part, the chemists first extracted a large volume of argon followed by nitrogen and oxygen using magnesium and red-hot copper. Though the air was already known to contain 99.5% of oxygen, argon and nitrogen, it was difficult to identify the remaining 0.05%. Travers and Sir William Ramsay studied liquefied air in 1898. In 1898 these scientists began to isolate different gasses. With the aim of discovering the missing noble gases in the periodic table, Morris M. Krypton was first discovered by British scientists WilliamRamsey, Morris Travis and John Rayleigh.
