    Electron configuration of Si; \[1s ^{2} 2s ^{2} 2p ^{6} 3s ^{2} 3p ^{2}\] If you draw an Energy Diagram(for Si) you'll see that the 3rd energy level (3s,3p,4s and 3d) has 4 electrons in total.

    |dw:1347892907941:dw| This is an energy diagram for Si. As you can see the 3rd energy level (n=3) has 2electrons in 3s and 2 electrons in 3p. 2+2=4 Did this help?
