Homework Answers
Ans is beryllium
According to the variation given, the highest difference is in between second and third ionization energy which means the removal of the third electron requires much higher energy than for 2nd electron which fits very well with the Be electronic configuration (1s2, 2s2). In this configuration, the energy required relatively low for first two-electron removal, after that third electron has to be removed from the 1s orbital which will require much higher energy as its electron is very near to the nucleus.
