SUMMARY
The electron configuration of the Ni+ ion is [Ar]3d9, contrary to the initial assumption of [Ar]4s13d8. This discrepancy arises because, upon ionization, one electron is promoted from the 4s orbital to the 3d orbital. The energy dynamics change due to electron shielding effects, where the 3d orbitals experience greater shielding than the 4s, leading to a higher binding energy for 3d in heavier transition metals. Quantum-mechanical calculations, such as those performed using Cowan's code, are essential for accurately determining these configurations.
