Transition metals are found to be good catalysts. Explain.

Transition elements and their compounds are found to be good catalysts. Give examples.

Why do transition metals and their compounds are found to be good catalysts and form alloys ?

Most of transition metals show variable oxidation states. Explain

Transition metals form mostly coloured compounds.Explain.

Transition element and their compounds exhibit paramagnetic behaviour and transition metals have high melting points. Explain.

How is the variability in oxidation states of transition metals different from that of the non transition metals? Illustrate with examples.

Why transition metals are generally coloured ?
