Find the correct statement about oxides of the Group 7 elements:
A) Manganese forms oxides only in lower oxidation states, i.e. +2, and +3.
B) Technetium and rhenium form oxides in higher oxidation states, +4, +6 and +7.
C) For all Group 7 elements oxides in oxidation states from 2 to 7 are well known.

Question

Quizplus · Accepted Answer

Technetium and rhenium, unlike manganese, form oxides in higher oxidation states such as +4, +6, and +7. This is because they have a wider range of stable oxidation states compared to the lighter elements in Group 7, which typically do not form stable oxides in such high oxidation states.
