Recall that the nucleus of an atom contains protons and neutrons. Protons carry a positive charge, while neutrons are neutral (no charge).
Since the nucleus contains protons, the overall charge of the nucleus depends on the number of protons present.
Neutrons do not affect the charge because they are electrically neutral.
Electrons, which carry a negative charge, are located outside the nucleus and do not influence the nucleus's charge.
Therefore, the charge of the nucleus is always positive due to the presence of protons.
