Match species given in Column I with electronic configuration given in

1.	Match species given in Column I with electronic configuration given in Column II {:("Column I","Column II"),((i) Cr,(a) [Ar] 3d^(8) 4s^(0)),((ii) Fe^(2+),(b) [Ar] 3d^(10) 4s^(1)),((iii) Ni^(2+),(c) [Ar] 3d^(6) 4s^(0)),((iv)Cu,(d) [Ar] 3d^(5) 4s^(1)),(,(e) [Ar] 3d^(6) 4s^(2)):}
Answer» Solution :`Cr = [AR] 3d^(5) 4s^(1), FE^(2+) = [Ar] 3d^(6) 4s^(2), Ni^(2+) = [Ar] 3d^(8) 4s^(6), CU = [Ar] 3d^(10) 4s^(1)`
