key term - Homonuclear diatomic molecules

Definition

Homonuclear diatomic molecules are molecules composed of two identical atoms bonded together. Examples include $\text{H}_2$, $\text{O}_2$, and $\text{N}_2$.

5 Must Know Facts For Your Next Test

  1. In homonuclear diatomic molecules, electron density is shared equally between the two atoms.
  2. These molecules have molecular orbitals that can be bonding or antibonding.
  3. The bonding in these molecules can be explained using Molecular Orbital Theory.
  4. $\sigma$ and $\pi$ molecular orbitals are formed through the linear combination of atomic orbitals.
  5. The bond order in homonuclear diatomic molecules can be calculated using the formula: $(\text{Bond Order} = \frac{1}{2}(\text{number of bonding electrons} - \text{number of antibonding electrons}))$.
