MCQ
A large difference between the fourth and fifth ionization energies indicates the presence  of
  • A
    $5$ valence electrons in an atom
  • B
    $6$ valence electrons in an atom
  • $4$ valence electrons in an atom
  • D
    $8$ valence electrons in an atom

Answer

Correct option: C.
$4$ valence electrons in an atom
c
The large difference between fourth and fifth ionization energies is due to The Atom can have $4$ electron excess to get stable. On losing the $4$ electrons it gets stability. So it cannot able to lose another electron easily that's why it has high fifth $I.P$
