#14#

Explanation:

The amount of electrons in an atom is equal to the atom's number of protons.

The number of protons in silicon is the same as the element's atomic number.

Since the atomic number of silicon is #14#, a single atom of silicon has #14# protons and #14# electrons.

Silicon's structure (simplified):

(Note that silicon also has #14# neutrons, but an atom's number of neutrons is not always equal to the amount of protons/electrons. This is a special case.)
