Krypton

  1. 1. 36 Kriptón – Krypton Mass: 83,80 u 1s2 2s2 2p63s23p64s23d104p6 Melting point: 115,79 K Boiling point: 119,93 K Density: 3,749 g/cm3 Discovery: 1898 Krypton, like the other noble gases, can be used in lighting andphotography. Krypton light has a large number of spectral lines, andkryptons high light output in plasmas allows it to play an important rolein many high-powered gas lasers (krypton ion and excimer lasers), whichpick out one of the many spectral lines to amplify. There is also aspecific krypton fluoride laser. The high power and relative ease ofoperation of krypton discharge tubes caused (from 1960 to 1983) theofficial length of a meter to be defined in terms of the 605 nm (red-orange) spectral line of krypton-86.
