As in the case of titanium, vanadium, and chromium, the highest oxidation state (+7) of manganese corresponds to the total number of 3d and 4s electrons. That state occurs only in the oxo species permanganate (MnO 4 − ), manganese heptoxide (Mn 2 O 7 ), and manganese trioxide fluoride (MnO 3 F), which show some similarity to corresponding ...
