Resonance

Resonance. A molecule or polyatomic ion for which 2 or more dot formulas with the same arrangement of atoms can be drawn is said to exhibit RESONANCE. Resonance Example. CO 3 2- 3 resonance structures can be drawn for CO 3 2- the relationship among them is indicated by the double arrow.

VSEPR Theory

VSEPR Theory. Molecular geometries. VSEPR Theory. Stands for valence-shell electron-pair repulsion theory States that because electrons repel each other, the molecular shape of the compound will change so that the valence electron pairs are as far away from each other as possible.
