Explanation.
Protons and electrons have same magnitude but opposite charges. If number of electrons and protons are equal in an atom, then such atom will be neutral due cancellation of opposite charges.As in this case of nitride ion, protons are 7 but electrons are 10, it means 3 electrons are greater than protons tin numbers, so there will be negative charge (-3).Note
Neutron are neutral.
