2.2.2 Bond order

Hydrogen contains a single bond.

Oxygen molecules contain a double-bond.

Diatomic Nitrogen contains a triple-bond.

The number of bonds between two atoms is known as the bond order. The more strength a bond has, the closer they are packed, thus the length decreases.

Strengthāˆ1lengthStrength \propto \frac{1}{length}

Bond strength and Bond length can be quanified. The stronger the bond, the larger the bond entalphy.

Bond length = the average distance between two bonded neclei.
