Transition-Metal Catalysts
One important use of transition metals and their compounds is as catalysts for a variety of industrial processes, mostly in the petroleum and polymer (plastics, fibres) industries, in which organic molecules are isomerized, built up from simple molecules, oxidized, hydrogenated, or caused to polymerize. Only a few of the most important such processes and their catalysts can be mentioned here. Catalysts are of two physical types: homogeneous (i.e., dissolved in the reaction mixture) and heterogeneous (i.e., constituting a solid phase separate from and insoluble in the reaction mixture). Both types are represented on the industrial scene, but the latter are much more common.

Due to the presence of these unpaired electrons, they show paramagnetism. Thus, transition metals are not diamagnetic. They are good conductors of heat and electricity. They form complexes and show variable oxidation state as d orbitals are gradually filled up in the transition series.
