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

The maximum oxidation state of an element depends on its group number and the number of valence electrons. For example, manganese (Mn) in Group 7 of the periodic table has an oxidation state of \( +7 \) in \( \text{MnO}_4^- \) (permanganate ion). Thus, \( +7 \) is the maximum oxidation state.
