Only one arrangement of d electrons is possible for metal ions with d⁷ configuration.

Question

Quizplus · Accepted Answer

The given electron configuration notation seems to be incorrect or not standard. However, assuming it attempts to describe a d^1 configuration (which is what "dS1" might imply if interpreting loosely), multiple arrangements are possible due to the presence of different orbitals within the d subshell where the single electron can reside, and also due to the effects of crystal field splitting in different coordination environments.
