Question

The successive ionisation energy (I.E.) of an element ‘X’ is given

Data given in KJ/mol.

Find out the group number of element X.

(1) Group → 3

(2) Group → 14

(3) Group → 2

(4) Group → 13

Answer 1

Correct option is : (3) Group \(\rightarrow\) 2

Since the ratio of \(\frac{IE_3}{IE_2}\) is maximum, so the element X belongs to group 2.
