Its low atomic mass, thermal conductivity, specific heat, and sound speed are greatest after hydrogen. Due to the small size of helium atoms, the diffusion rate through solids is three times greater than that of air and 65% greater than that of hydrogen.

Comme il n'a pas de sous-couches capables de réagir, c'est (avec le néon) le moins réactif de tous les corps simples . L'hélium peut néanmoins former des composés instables (excimères) avec le tungstène, l'iode, le fluor, le soufre et le phosphore en phase plasma, par décharge ou d'une autre manière.
