Izotopi vodonika

Izotopi su atomi istog elementa, koji se razlikuju po broju neutrona u nukleusu, dakle imaju razlicite masene brojeve i razlicite relativne atomske mase.

Znaci Ar vodonika bi isle zaokruzeno 1, 2 , 3?

Hvala!  :)

Dakle, zaokruzene relativne atomske mase izotopa vodonika bi bile:

protijum-Ar=1
deuterijum-Ar=2
tricijum-Ar=3

Medjutim, kako u prirodnoj smesi vodonika najvise ima protijuma, oko 5000x manje deuterijuma i jos mnogo mnogo manje tricijuma, Ar vodonika se navodi 1.008.
