Krypton difluoride, KrF 2 is a chemical compound of krypton and fluorine. It was the first compound of krypton discovered. [2] It is a volatile, colourless solid at room temperature. The structure of the KrF 2 molecule is linear, with Kr−F distances of 188.9 pm. It reacts with strong Lewis acids to form salts of the KrF + and Kr 2 F + 3 ...
Its lighter neighbor, krypton also forms well-characterized compounds, e.g., krypton difluoride. Krypton tetrafluoride was reported in 1963, [104] but was subsequently shown to be a mistaken identification; the compound seems to be very hard to synthesize now (although even the hexafluoride may exist). [105]
Krypton compounds with other than Kr–F bonds (compounds with atoms other than fluorine) have also been described. KrF 2 reacts with B(OTeF 5) 3 to produce the unstable compound, Kr(OTeF 5) 2, with a krypton-oxygen bond.

Calcium difluoride is a notable compound. In the form of the mineral fluorite it is the major source of commercial fluorine. It also has an eponymic crystal structure, which is an end member of the spectrum starting from bixbyite and progressing through pyrochlore .
Krypton(IV) fluoride is a hypothetical inorganic chemical compound of krypton and fluorine with the chemical formula KrF 4. At one time researchers thought they had synthesized it, but the claim was discredited. [1] The compound is predicted to be difficult to make and unstable if made. [2]
Krypton, like the other noble gases, is used in lighting and photography. Krypton light has many spectral lines, and krypton plasma is useful in bright, high-powered gas lasers (krypton ion and excimer lasers), each of which resonates and amplifies a single spectral line. Krypton fluoride also makes a useful laser medium.
Neon compounds are chemical compounds containing the element neon (Ne) with other molecules or elements from the periodic table.Compounds of the noble gas neon were believed not to exist, but there are now known to be molecular ions containing neon, as well as temporary excited neon-containing molecules called excimers.
