The maximum oxidation state of an element in the first transition series never exceeds its group number.

Question

Quizplus · Accepted Answer

This statement is true based on the electronic configurations of elements in the first transition series. The maximum oxidation state is determined by the number of valence electrons available for bonding, which is equal to the group number for these elements. For example, the maximum oxidation state for iron (Fe) is +6, which corresponds to the six valence electrons in the 6th group.
