Give examples and suggest reasons for the following features of the transition metal chemistry : (i) The lowest oxide of transition metal is basic, the highest is amphoteric/acidic. (ii) Atransition metal exhibits highest oxidation state in oxides and fluorides. (iii) The highest oxidation state is exhibited in oxonanions of a metal.

(1)in case of low oxidation state metals have free electron and thus behaves as abase whereas in case of high oxidation state deficency of electron and thus can accept electron and thus behaves as an acid

(2)because of their high electronegativity and small size .for ex-OsF6,V2O5

(3)because of their high electronegativity and small size.o oxoanion have the highest oxidation stateMnO4-
