Sodium atoms have the largest second ionization energy.
When sodium loses one electron, it formsNa+ion which has stable electronic configuration of the noble gasNe.

WhenNa+ions loses an electron, this stable configuration ofNeis broken. This requires high amount of energy. Hence, second ionization energy of sodium is largest.
