D

Verified step by step guidance1
Recall that the charge of an atom depends on the balance between the number of protons and electrons it contains.
Protons carry a positive charge (+1), electrons carry a negative charge (-1), and neutrons are neutral (no charge).
If an atom has more electrons than protons, it will have a net negative charge (an anion).
If an atom has equal numbers of protons and electrons, it is electrically neutral.
Therefore, for an atom to have a positive charge, it must have more protons than electrons, resulting in a net positive charge.
