When determining the total binding energy of an atom I understand the method to be as follows:(adsbygoogle = window.adsbygoogle || []).push({});

The total mass of all nucleons added together

minus

The total mass of the atom minus the mass of the electrons

My question is, how do you determine the number of electrons in an atom? All the questions I have done of this nature so far seem to be using one electron for the calculations. Thanks.
