The first four ionization energies of an element are 738 kJ/mole, 1450 kJ/mol, 7700 kJ/mol and 11000 kJ/mol. Identify the periodic group to which this element belongs.

Explanation

To determine the periodic group of the element based on its ionization energies, we can follow these steps:

### Step-by-Step Solution:

1. **List the Given Ionization Energies**:
- First Ionization Energy (IE1) = 738 kJ/mol
- Second Ionization Energy (IE2) = 1450 kJ/mol
- Third Ionization Energy (IE3) = 7700 kJ/mol
