Select the material containing the element with the highest oxidation number and determine how many electrons are required to reduce that element to an oxidation number of zero.

Question

Quizplus · Accepted Answer

The material with the element with the highest oxidation number is likely to be a compound containing an element in its highest possible oxidation state. Among the given choices, the only element that can exhibit a high oxidation number is manganese (Mn). In the compound KMnO4, for example, Mn has an oxidation number of +7. To reduce Mn to a zero oxidation state, 7 electrons would be required (each electron reduces the oxidation state by 1). Therefore, the correct answer is B) 7.
