Vedclass · Answer

(A) True: Transition elements have $(n-1)d$ and $ns$ electrons with comparable energies,allowing them to show variable oxidation states.$(b)$ True: The $E^o$ values for $Mn^{2+}/Mn$,$Zn^{2+}/Zn$,and $Ni^{2+}/Ni$ are more positive than expected due to factors like high hydration enthalpy or stable electronic configurations $(d^5, d^{10})$.$(c)$ True: The high electronegativity and small size of oxygen and fluorine (in chlorides/fluorides) stabilize the highest oxidation states of transition metals.
