Hi there,
The atomic number of an element, also called a proton number, tells you the number of protons or positive particles in an atom. ... That means an atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons.
Good luck my dude!
