For ""^1H, Z, the atomic number = 1.

Explanation:

Z defines the number of massive, positively charged, nuclear particles, and thus determines the identity of the element: Z=1, hydrogen, Z=2, helium.........Z=23, vanadium.

Most hydrogen nuclei have no neutrons in their nuclei, i.e. the ""^2H, ""^3H isotopes are rare, and thus there are no neutrons in ""^1H. IF there is one positive charge in the nucleus, the NEUTRAL element must contain 1 electron, which is conceived to whizz about the nucleus. Why must there be 1 electron in the neutral element?
