Question

How to calculate nuclear spin quantum number of hydrogen?

Answer 1

The rules for determining the net spin of a nucleus are as follows;

If the number of neutrons and the number of protons are both even, then the nucleus has NO spin.

If the number of neutrons plus the number of protons is odd, then the nucleus has a half-integer spin (i.e. 1/2, 3/2, 5/2)
