The statement that best explains why hydrogen’s atomic number is equal to its mass is:
**Hydrogen does not have any neutrons.**
This is because the atomic number of an element is defined as the number of protons in its nucleus, and for hydrogen, which has one proton and no neutrons, the atomic mass is approximately 1, making the atomic number (1) equal to its mass number (1).
