Catalytic Property :- Transition element shows catalytic property due to following reason
(a) Such elements are in solid state so reaction is taken on its surface.
(b) Tendency to show variable oxidation state.
(c) Presence of empty d-orbital.
(d) They have small size.
Ex:- Pd,Pt,Ni,Co Mn V are the most popular transition metal with shows catalytic mental with shows catalytic property.
Formation of complex compound :-Transition mental has great tendency to form complex compound. It is due to following reason
(a) Such elements have high charge density.
(b)They have smaller ionic size.
(c) They have empty d-orbital.
(d) They have to show variable oxidation state
Formation of interstitial compound :-d-block elements have crystalline structure. In its crystal structure various voids are present which is occupied by the element has smaller size like H,C etc. then such compound is called interstitial compound. Such compound has different property with respect to the metal like
(a) It has high tensile strength.
(b) Such compounds are more chemically inert.
(c) Electrical conductivity is maintain.
