Electronic configuration

The following represents the electronic configuration and its associated term symbol for the ground state neutral gaseous atom. The configuration associated with silicon in its compounds is not necessarily the same.

• Ground state electron configuration:  [Ne].3s².3p²
• Shell structure:  2.8.4
• Term symbol:   ³P₀
