Identify the group number of silicon (Si) in the periodic table. Silicon is in group 14 (or group IV) of the periodic table.
Recall that the group number for main group elements corresponds to the number of valence electrons for that element.
Since silicon is in group 14, it has 4 valence electrons.
Understand that valence electrons are the electrons in the outermost shell of an atom and are important for chemical bonding.
Therefore, silicon has 4 valence electrons.
