Hydrogen has three isotopes 1h, 2h, and 3h. what is the difference between these three isotopes?

the differences are: molecular weight, neutron number, melting point and boiling point.

Explanation:

Isotopes are elements that have the same number of protons. There are 3 known hydrogen isotopes, the propium (H, which is hydrogen itself), deuterium (2H, commonly called D) and tritium (3H, commonly called T), which, although they have very similar characteristics, have some characteristics. different, such as molecular weight, neutron number, melting point and boiling point.
