# According to MO theory, what does the overlap of two s atomic orbitals produce?

Nov 19, 2016

It makes one ${\sigma}_{n s}$ and one ${\sigma}_{n s}^{\text{*}}$ molecular orbital (MO). These are known as bonding and antibonding MOs, respectively.

A simple depiction of these MOs is in an MO diagram:

And a depiction of $n s$ sigma bonding and $n p$ pi bonding is:

The overlap of 2 atomic orbitals produces molecular orbitals

#### Explanation:

The 2 MO are the bonding and the antibonding molecular orbitals
