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 hydrogen has an atomic number of 1 (indicating it has one proton) and its most common isotope (protium) has no neutrons. Therefore, its atomic mass, primarily based on its single proton, is approximately 1.
