Question

Among VA group elements, the element which has highest ionization energy?

• A. $N$
• B. $P$
• C. $Sb$
• D. $Bi$

Answer 1

The correct option is 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.
