Krypton

Chemical reactions


Reaction of krypton with halogens


Krypton will react with fluorine, F2, when cooled to -196 °C (liquid nitrogen) and zapped with an electric discharge or X-rays, forming krypton(II) fluoride, KrF2.

Kr(s) + F2(s) KrF2(s)

This compound decomposes when heating to room temperature.

The other halogens do not react with krypton.

Reaction of krypton with the water


Krypton does not react with water, but is slightly soluble; approximately 59.4 cm3/kg at 20 °C (293 K) [1]
