Question

Choose CORRECT outer electronic configuration of Cu,Cr &Pd are respectively. (A) 3d104s1,3d54s1,4d105s0 (B) 3d94s2,3d44s2,4d85s2 (C) 3d104s1,3d54s1,4d85s2 (D) 3d94s1,3d54s2,4d105s0

Fully filled and half-filled orbitals are more stable. The configurations are given below. Copper: [ Ar ] 3d104s1 so the outer electronic configuration is 3d104s1 Chromium: [.Ar].3d54s1 so the outer electronic configuration is 3d54s1 Palladium: [.Kr].4d105s0 so the outer electronic configuration is 4d105s0
