Behavior: These elements were considered to be inert gases until the 1960s, because their oxidation number of zero prevents the noble gases from forming compounds readily.

The first concerns noble gases. Were it not for escape, chemically unreactive gases such as neon or argon would remain in an atmosphere indefinitely.

Based on information from noble gas, noble gases in the atmosphere are originated from mantle degassing.

They are the noble gases: neon, argon, krypton, xenon, and radon.

The study indicates strong composition differences between noble gases from MORB and OIB supporting two-layer mantle structure. Mantle degassing process is controlled mainly by SCD model.

Inert atmosphere ovens use noble gases, such as nitrogen and argon, to prevent oxidation caused by high temperatures.

There are also tiny traces of other noble gases besides argon, namely, neon, krypton, and xenon.

So do you think noble gases would have a high positive electron affinity, a low positive, or negative electron affinity?

His doctoral thesis was devoted to the geochemistry, geochronology and nuclear chemistry of the noble gases xenon and krypton.
