The charge of the electron is about -1.60217733 x 10-19 C, the charge of the proton is equal and opposite to that of the electron, both charges are constant.
Subtract the number of electrons from the number of protons. In an atom, each proton has a charge of +1, each electron a charge of -1, and each neutron has no charge. If there's one more proton than electron, the overall charge is +1. An example of this is a sodium ion. The ion has 11 protons, but only 10 electrons, so 11-10 = +1.
