Sodium, Na atoms have the largest second ionization energy.


When sodium loses one electron, it forms Na+ ion which has the stable noble gas configuration of Ne.

When Na+ ions lose an electron, this stable configuration of Ne is broken. This requires a high amount of energy. 
 
Hence, the second ionization energy of sodium is the largest.
