Question

Silicon has 4 electrons in its outer most orbit. In forming the bond:

• A. it gains electrons
• B. it loses electrons
• C. it shares electrons
• D. none of the above

Answer 1

The correct option is C it shares electrons

Silicon has 4 electrons in its outer most orbital in forming the bond:-

Si =${1s}^2$${2s}^2$${2p}^6$${3s}^2$${3p}^2$

It has 4 electrons in its outermost shell and need 4 more to complete its octet and become stable. Thus, Silicon atoms form 4 covalent bonds with 4 neighboring atom. In each covalent bonding 1 electron is shared by 2 atoms.

Hence silicon share its electrons.
