Like its fellows, krypton is a colourless, odourless, tasteless, noble gas that occurs in trace amounts in the atmosphere. Like the other noble gases, it too is useful in lighting and photography, and its high light output in plasmas allows it to play an important role in many high-powered lasers.
Krypton was first discovered by Sir William Ramsay and Morris Travers on May 30, 1898. It has an atomic symbol Kr and atomic number 36. Due to the high cost of isolating krypton, the element has few practical uses. It is used in certain types of high-speed photography. As it is one of the noble gases, krypton was thought to be inert and unable to form compounds. Krypton does have the ability to form a few compounds, including Krypton difluoride.
