MCQ
Among $VA$ group elements, the element which has highest ionization energy?
  • ✓
    $N$
  • B
    $P$
  • C
    $Sb$
  • D
    $Bi$
✓

Answer

Correct option: A.
$N$
Among $VA$ group elements, the element which has highest ionization energy is nitrogen.
The ionization energy of $VA$ group elements decreases on moving down the group $($from $N$ to $Bi),$ due to gradual increase in atomic size.
