Describe the structure of metallic lattices
WebThe cations and anions in an ionic solid are arranged in a lattice structure that maximizes the attractive forces between opposite charges and minimizes the repulsive forces between like charges. In this video, we'll learn how to represent the structure of an ionic solid using a particulate model. Created by Sal Khan.
