The atomic number is calculated by calculating number of protons in an element. example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.

Atomic number is determined by the number of protons present in the nucleus of an atom.The atomic number is equal to the number of protons in an atom. For example, hydrogen has an atomic number of 1 because it has one proton. Similarly, carbon has 6 protons in its nucleus so its atomic number is 6.
