Pbs Learning Media: Ionic Bonding
In this interactive activity from ChemThink, students will learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.
PBS
Pbs Learning Media: Covalent Bonding
This interactive activity from ChemThink takes a closer look at a covalent bond: how it is formed and how the sharing of two electrons can keep atoms together.
