First three ionisation energies (in kJ/mol) of three representative elements are given below:

Element     IE1                    IE2                   IE3

P               495.8                4562                  6910
Q               737.7               1451                   7733
R               577.5                1817                  2745

Then incorrect option is :

1. Q: Alkaline earth metal.

2. P: Alkali metal.

3. R: s-block element.

4. All three: P,Q & R belong to the same period.
