The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't dissolve into minerals the way other gases do.

Researchers led by Colin Jackson, a graduate student in geological sciences, have found noble gases to be highly soluble in...
