Kare oxidation state ka samadhan part 2

Oxidation States

Manganese in the +2 oxidation state is more stable than +3 oxidation state where as iron is stable at +3 oxidation state than +2 oxidation state. Explain why

Write the different oxidation states of iron. Why +2 oxidation state of manganes is more stable ? (Zof Mn =25).

Higher oxidation state of manganese in fluoride is +4 (MnF_(4)) but highest oxidation state in oxides is +7(Mn_(2)O_(7)) because

The most stable +2 oxidation state in Lanthanides is

The oxidation state of O-atom is +2 in
