Explanation / Answer
Since, upto the ionization of 4th electron the required successive energy is slightly increased but after 4th electron the ionization energy is really high, this is becauae the atom has attained inert gas configuration after the ionization of fourth electron.
So the element E belongs to carbon family, which is group 14.
