Electron Configuration of Silicon

Basic properties of silicon (Figure 2)

Elements are arranged from left to right by atomic number. Silicon has atomic number 14 and belongs to Period 3, Group 14. With shell capacities of K (2), L (8), M (18), and N (32), its electrons fill the K-shell 1s orbital, the L-shell 2s and 2p orbitals, and the M-shell 3s orbital. The remaining two electrons occupy 3p orbitals.
