This multimedia lesson for Grades 7-8 features six animations, one video, and a hands-on lab to explore the process of ionic bonding. Learners can visualize what happens when positive and negative ions attract each other and form a bond, build 2D and 3D models, and perform a hands-on activity to observe sodium chloride crystals and relate their shape to the molecular model. Editor’s Note: Ionic bonding occurs when electrons are transferred between atoms through electrostatic attraction between two oppositely charged ions. Covalent bonding occurs when electrons are shared between atoms. The processes are quite different. This module very effectively explores the atomic processes that underlie ionic bonding.
