(ii) Transition metals generally from coloured compounds. Transition metal catalysts have played a vital role in modern organic 1 and organometallic 2 chemistry due to their inherent properties like variable oxidation state (oxidation number), complex ion formation and catalytic activity. (iii) Transition metal atoms or ions generally form the complexes with neutral, negative and positive ligands. Transition metals and their compounds act as catalysts because their electronic configurations enable them to temporarily exchange electrons with reacting species. Explain why transition metals and their many compounds act as goodd catalyst. (ii) The enthalpies of atomisation of the transition metals are high. Transition metals and their many compounds act as good catalyst. (ii) The enthalpies of atomisation of the transition metals are high. Iron in the Haber ⦠These elements are well-known for their various oxidation states, which is possible due to the presence of the valence electrons (electrons that form compounds by joining with other elements) ⦠They also are good conductors of heat and electricity. 1 Answer to Transition metals and their many compounds act as good catalyst.
