Problem

The trend in second ionization energy for the elements from lithium to fluorine is not a smooth one. Predict which of these elements has the highest second ionization energy and which has the lowest and explain. Of the elements N, O, and F, O has the highest and N the lowest second ionization energy. Explain.

Solution

Ionization energy is the energy required to remove an electron from a gaseous element. 

The second Ionization energy basically means it is the energy required to remove the second electron.

The trend for ionization energy is shown below:
