Question

Quizplus · Accepted Answer

Chromium belongs to Group 6 elements of the Periodic Table. It has six valence electrons in its outermost shell. Thus, the maximum oxidation state of chromium is +6, where it loses all its valence electrons. However, +6 oxidation state is a highly unstable state for chromium, so it mostly exhibits +2 or +3 oxidation states. Therefore, the correct answer is (B) +6.
