if there is 63 protons,89 neutronsand 60 electrons so what is his net charge
To determine the net charge of an atom, we need to consider the number of protons and electrons.
Protons carry a positive charge (+1), while electrons carry a negative charge (-1). Neutrons, on the other hand, have no charge and do not contribute to the net charge of an atom.
In the given case, there are 63 protons (which contribute a charge of +63) and 60 electrons (which contribute a charge of -60). To find the net charge, we subtract the total negative charge from the total positive charge:
+63 (+ protons) - 60 (- electrons) = +3
Therefore, the net charge of the atom in this case is +3.
