MCQ
How many ionisation energies can carbon have
  • A
    $1$
  • B
    $2$
  • ✓
    $4$
  • D
    $6$
✓

Answer

Correct option: C.
$4$
c
(c) The energy required to remove an electron from outermost orbit of an isolated gaseous atom is called $I.E.$ Now carbon has $4{e^ - }$ in outermost shell. Thus it has $4$ ionization energies.
