The best statement that explains why hydrogen’s atomic number is equal to its mass is:

**Hydrogen does not have any neutrons.**

This is because hydrogen has one proton (which gives it an atomic number of 1) and typically no neutrons, resulting in a mass number of 1 (the number of protons in the nucleus).
