WebAtommasse Atommassen angiver massen af samtlige protoner, neutroner og elektroner, som et atom indeholder. Atommassen er altså forskellig for de forskellige grundstoffer såvel som for grundstoffernes forskellige isotoper. Derfor afhænger et grundstofs atommasse af forekomsten af grundstoffets forskellige isotoper. WebAtommasse Summen af det totale antal protoner, ”Z” og det totale antal neutroner, ”N”, kaldes for atommassen. Symbolet herfor er ”A”. Ikke alle atomer af samme grundstof har samme atommasse, for selvom antallet af protoner, Z, altid er det samme, så kan antallet af neutroner og dermed atomets samlede masse godt variere.
