The successive 5 ionisation energies of an element are $800,2427,3658,25024$ and $32824 \mathrm{~kJ} / \mathrm{mol}$, respectively. By using the above values predict the group in which the above element is present:
Select the correct option:
A
Group 14
B
Group 4
C
Group 2
D
Group 13
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
The $\mathrm{IE}_{4}$ is suddenly very high therefore element must have 3 valence $\mathrm{e}^{-}(\mathrm{s})$ and it belong to group 13
