What is the electron configuration of silicon?

The element silicon (atomic number 14) has the following electron configuration :

- Full configuration: 1s2 2s2 2p6 3s2 3p2 - Compressed (without all standard script numbers): 1s2 2s2p6 3s2p2

- Noble Gas form : [Ne] 3s2 3p2 / [Ne] 3s2p2 (this works because [Ne] symbolizes the electronic configuration of Neon, which is 1s2 2s2 2p6. When added to 3s2p2, it is equivalent to the full electron configuration of Silicon, when neutral.)
