Covalent bond

The video tutorial explains how pairs of electrons form molecules through covalent bonds. It describes how single, double, and triple covalent bonds are created by sharing one, two, or three pairs of electrons, respectively. The tutorial also highlights that covalent bonds typically occur between nonmetal atoms, which need to gain electrons to achieve a full outer shell.

Between which types of atoms do covalent bonds typically form?
