MCQ
Silicon has $4$ electrons in the outermost orbit. In forming the bonds
  • A
    It gains electrons
  • B
    It loses electrons
  • ✓
    It shares electrons
  • D
    None of these
✓

Answer

Correct option: C.
It shares electrons
c
To complete an octet, silicon requires $4$ more electrons. So, in bonding, it shares its electrons. Removing $4$ electrons from silicon is difficult.
