प्रश्न
Name the elements of 3d transition series that show maximum number of oxidation states. Why does this happen?
उत्तर
In 3d-series of transition metals, manganese has an atomic number of 25 that gives the electronic configuration as [Ar] 3d54s2 ,where we see that the maximum number of unpaired electrons is found in manganese atom; so, it can show a maximum oxidation state upto +7.
