Question

Which configuration represents an excited state configuration (one which is not a ground state, yet does not violate the Paul

Answer 1

Answer #1

1) [Ar] 4s¹ 3d⁵ = which is having the electron configuration of Chromium [ Ground state ]

2) [Ar] 4s² 4p¹ = excited state because after 4s, 3d will come not 4p

3) [Xe] 5s² 5p¹ = not valid there is no such arrangement

4) [Xe] 6s² 4f⁷ = which is having the electron configuration of Europium [ Ground state ]

5) [Rn] 7s² = which is having the electron configuration of Radium [ Ground state ]
