Consider the following ionization enthalpies of two elements 'A' and 'B'.
Which of the following statements is correct ?
| Element | Ionization enthalpy (kJ/mol) | ||
| $\displaystyle 1^{\text {st }}$ | $\displaystyle 2^{\text {nd }}$ | $\displaystyle 3^{\text {rd }}$ | |
| A | $\displaystyle 899$ | $\displaystyle 1757$ | $\displaystyle 14847$ |
| B | $\displaystyle 737$ | $\displaystyle 1450$ | $\displaystyle 7731$ |
Official answer
(3)
Both 'A' and 'B' belong to group-$\displaystyle 2$ where 'B' comes below 'A'.
