Start with the electron configuration of neutral Ni: [Ar] 3d8 4s2 Then remove one electron for the Ni+ ion: [Ar] 3d8 4s1 Next, add the electron configurations of each ion or atom listed in the compound: S1: 1s2 2s2 2p6 U1: [Rn] 5f3 6d1 7s2 P12: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3 S1: 1s2 2s2 2p6 S1: 1s2 2s2 2p6 P0: 1s2 2s2 2p6 F1: 1s2 2s2 2p5 F1: 1s2 2s2 2p5 F1: 1s2 2s2 2p5 S1: 1s2 2s2 2p6 S1: 1s2 2s2 2p6 U1: [Rn] 5f3 6d1 7s2 P1+: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 S1: 1s2 2s2 2p6 S1: 1s2 2s2 2p6 P0: 1s2 2s2 2p6 F1: 1s2 2s2 2p5 F1: 1s2 2s2 2p5 F1: 1s2 2s2 2p5 S1: 1s2 2s2 2p6 S1: 1s2 2s2 2p6 Put all the electron configurations together and simplify using noble gas notation where possible: [Ar] 3d8 4s1 3p6 3d10 4p6 [Rn] 5f3 6d1 7s2 This is the ground-state electron configuration of the ion. The correct answer is choice C: [Ar] 3d ⁸
