Answer:The correct answer is A. -3Explanation.Protons and electrons have the same magnitude but opposite charges. If the number of electrons and protons are equal in an atom, then the atom will be neutral due to the cancellation of opposite charges.As in this case of nitride ions, protons are 7 but the electrons are 10, which means 3 electrons are larger than protons tin numbers, so that there will be no negative charge (-3).NoteNeutron are neutral.
