Those are mass numbers of each molecular isotope, meaning those of
It doesn't mean that there are three naturally-existing atomic isotopes, but it does mean that one
Add up the mass numbers and you should see that:
79+79=158
79+81=160
81+81=162
That means you have the three naturally-existing isotopic molecules:
7935Br−7935Br
7935Br−8135Br
8135Br−8135Br
Therefore, you still have:
- Two naturally-existing atomic isotopes.
- Due to the diatomic nature of naturally-existing bromine liquid, three combinations of atoms are possible, generating three naturally-existing molecules containing the three different combinations of atomic isotopes.
