For most of the 1st row transition metal elements, the ground state is: [Ar]3dx4s2 (4s fills first) …because e-e repulsion is decreased by filling the diffuse 4s orbital first. Note exceptions often occur with: Exactly ½-filled and full shells Chromium 3d5 4s1 Copper 3d10 4s1 These exceptions reflect a quantum mechanical stabilization of
