Final answer:
The net force resulting from the sum of attractive and repulsive forces between charged atoms in a crystal lattice is known as the electromagnetic force. This force holds together oppositely charged particles and repels particles of the same charge. In ionic solids, positive ions experience attraction from ions of opposite charge and repulsion from ions of the same charge.
Step-by-step explanation:
The net force resulting from the sum of attractive and repulsive forces between charged atoms in a crystal lattice can be referred to as the electromagnetic force. This force is responsible for holding together oppositely charged particles (electrons and protons) and repelling particles of the same charge. In an ionic solid, positive ions experience attraction from ions of opposite charge and repulsion from ions of the same charge.
