For an element, the successive ionization enthalpies are given below (in kJ/mol):

| I.E.1 | I.E.2 | I.E.3 | I.E.4 | |---|---|---|---| | 578 | 1810 | 2750 | 11580 |

How many electrons are present in the valence shell of this element?

Answer: 3

Solution

There is a huge jump in ionization energy between I.E.3 (2750) and I.E.4 (11580), indicating that the fourth
