Octet Rule. Before we start this lesson on Lewis dot structures and the octet rule, let’s review a bit. Atoms are composed of protons and neutrons that live in the nucleus and electrons that orbit.

Molecules have 3-dimensional shapes, and chemists use valence shell electron repulsion (VSEPR) theory to predict these shapes. VSEPR is based on the idea the electron pairs repel each other (similar.

Lewis structures were devised by chemist Gilbert Lewis. He is accredited with the discovery of covalent bonds, which is where atoms share electrons in groups of two. Two shared electrons in a Lewis.
