"Web1 day ago · However, helium was surprisingly placed among alkaline earth metals. This shift can be justified by the outer electron structure of helium, which, like the other members of the alkaline earth group, has two such electrons. However, from a chemical point of view, helium, like noble gases, is the least reactive of all elements in the periodic table. " - Electron shell diagram of helium
