Question

Quizplus · Accepted Answer

The given electron configuration is incorrectly formatted with characters like "S" and "U" that don't belong in electron configurations. However, the correct interpretation seems to aim towards a transition metal, given the presence of a "4d" subshell being partially filled, which is characteristic of transition metals. Transition metals are defined by having an incomplete d subshell in one or more of their oxidation states.
