WebHelium is een edelgas en als zodanig in vrijwel alle omstandigheden chemisch inert, maar wanneer helium gebombardeerd wordt met elektronen kan het verbindingen aangaan met wolfraam, jodium, fluor, zwavel en fosfor. Van alle gassen lost helium het slechtst op in water. Helium-3 is het product van radioactief verval van tritium.
