Both. The number of protons is the same as the number of electrons, so their positive and negative charges cancel out and an atom is stable overall (unless it's an ion, etc.).

But when describing isotopes, you'd refer to elements having a different number of neutrons and the same number of protons.

isotopes are elements that have the same number of protons, same number of electrons, but different mass of neutrons so that their CHARGE is the SAME

but their MASS is DIFFERENT
