Mark · Answer 1

A first row transition has electrons in its s orbital and its d orbital. The first electrons that it loses are the s electrons, since they are easiest to lose. So the metal loses two electrons, and has 4 in the 3d shell then it has total of 6 electrons in the ground state. So, the metal might be Chromium (Cr).
