Helium-3

Helium-3 (též helium 3, značka 3He, někdy nazývané také tralfium) je lehčí a mnohem méně běžný izotop helia, tvoří asi 0,000 137 % helia v přírodě. Jeho jádro se skládá z 2 protonů a 1 neutronu. Jedná se, spolu s vodíkem-1, o jeden ze dvou stabilních nuklidů, které mají v jádru více protonů než neutronů.
