[Edit]
The normal electron configuration of zinc is [Ar] 3d10 4s2, with 2 4s orbital electrons and 10 3d orbital electrons. By ionizing Zn and removing two electrons, the outer most electrons, the ones with the higher quantum number, are removed first, thus the two 4s orbital electrons are removed resulting in: [Ar] 3d10.
