Ionic & Covalent Bonding
Why do atoms bond at all? An isolated atom (except a noble gas) is high in energy and chemically restless. By joining with others it can reach a lower…
Start this topic → 2VSEPR & Valence Bond Theory
Lewis structures tell us which atoms are bonded, but not the shape of a molecule. Two theories fill this gap: VSEPR predicts geometry from electron re…

Valence bond theory pictures electrons staying on their own atoms, but it cannot explain why O 2 is paramagnetic. Molecular Orbital Theory (MOT), deve…
