  • Octet rule states that main-group elements will generally form enough bonds to obtain 8 electrons in their valence shell

  • Nonmetals starting from period 3 to 7 can have more than 8 valence electrons around them when in the center which makes them having an expanded octet

  • For POCl3, valence electron of P is 5, O is 6 while Cl is 7. Total valence electrons are 32. (5 + 6 + 7(3) = 32)
