The average silicon atom has fourteen protons, fourteen electrons, and most have 14 neutrons.
This is a digram of a silicon atom. This shows the 14 protons in the nucleus and where the 14 electrons are located. The four electron, highlighted in green, that are located in the outer ring are the valence electrons.
This diagram goes into detail on where the protons, neutrons, and electrons are located.
The electron configuration of silicon is 1s2 2s2 2p6 3s2 3p2.
This picture does a good job at showing that there are fourteen protons (P) and fourteen neutrons (N) in the nucleus of the silicon atom. It also does an nice job of showing on which level the fourteen electrons are located.
