In order to complete its octet silicon has 4 electrons. The valence electrons in silicon are 4 in number.
Silicon has been the blue-grey lustrous metalloid. Silicon has been used as a semiconductor in various computer chips, engine blocks, and cylinder heads. Silicon has been the element 14 in the periodic table.
The electrons have been filled in the shells of the atom in the predefined order. The shells are filled as 2 electrons in k orbital, 8 electrons in l orbital, 8 electrons in another m orbital.
Every element tends to complete its orbital. The electrons that are available by the element for bonding have been termed Valence electrons.
The electrons in Silicon are 14. They can be filled as:
2,8,4
There are 4 electrons available in silicon to form a bond in order to complete its octet. Thus there are 4 valence electrons in Silicon.
