Question

What is the maximum oxidation state of an element in the periodic table?

• A. \( +7 \)
• B. \( +6 \)
• C. \( +5 \)
• D. \( +4 \)

Hint:

The maximum oxidation state of an element typically corresponds to its group number for elements in the s and p blocks. However, transition metals can exhibit higher oxidation states.

Answer 1

The Correct Option is A

An element's highest possible oxidation state is determined by its group number and the count of its valence electrons. For instance, manganese (Mn), located in Group 7 of the periodic table, exhibits an oxidation state of \( +7 \) within the permanganate ion (\( \text{MnO}_4^- \)). Consequently, \( +7 \) represents its maximum oxidation state.
