What would be the charge if an atom contains 15e and 16p?

Answer 1

Add up, knowing that p's are Positive and e's are nEgative: +1

16p(= '+') + 15e(= '-') makes (+16) + (-15) = +1

So the overall charge of this 'particle' is +1

(If it were a chemical particle it would have been the NON-existing S+ ion)

Answer 2

The charge of an atom is determined by the difference between the number of protons and electrons. In this case, the atom contains 16 protons and 15 electrons, resulting in a net positive charge of +1.
