These are the seven noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). The first six exist naturally on Earth, but oganesson, which is ...

This led to the preparation of an extended number of noble gas fluorides and their derivatives, as well as fluorides of krypton and radon. Owing to its small atomic size and covalent behaviour ...

For example, such as data on the noble gases argon, krypton, and xenon, on the likely wall material tungsten, and on other possible impurities. Much of the work in this CRP focused on possible ...

Radioactive krypton, Kr-85 1, has been used for measuring the rate of rare-gas clean-up in pre-T.R. valves, with promising results. Krypton-85 has a half-life of ten years and emits mainly beta ...

Argon, krypton and xenon are very unreactive. They replace the air inside the lamp, preventing the metal wire from burning away.
