Answer 2

The number of protons in the nucleus of an atom of this element will determine its atomic number. Only this.
If the atom is not charged (in other words, not an ion), this is the same as the number of electrons in the atom. In that case, the number of electrons will be the same as the number of protons. But it is the proton count that sets or determines atomic number.
