WebHelium. Helium is het kleinste van alle elementen: omdat de kern meer lading heeft dan bij waterstof bevinden de elektronen zich in een iets 'strakkere' baan. Helium is een inert, niet reactief, kleurloos mono-atomair gas. Na waterstof is helium het meest voorkomende element van het heelal. Het is het lichtste edelgas, bekend als vulling van ...
