To what extent do the electronic configurations decide the stability of oxidation states in the first series of the transition elements? Illustrate your answer with examples.

THE ELEMENT in the first half of the transition series exihibit many oxidation state ex-mn(+2 to +7)stability of +2 oxidation state increases with increase in atomic number however sc does not show +@ oxidation state.it forms stable +3 oxidation state asby losing electron it attains noble gas configuration and v+5 are very stable for the same reason mn+2 is very stable due to attainment of half filled orbital
