What is Transition Metal?
An element in groups 3-12 of the periodic table, defined by IUPAC as elements whose atoms or ions have incompletely filled d-subshells. Transition metals often form colored compounds and ions, exhibit multiple oxidation states, and form stable complexes with ligands.

Transition metals are vital industrial catalysts (iron in Haber process, vanadium in Contact process, platinum in catalytic converters). They are used in alloys including steel (iron-carbon), bronze (copper-tin), and brass (copper-zinc). Transition metal compounds are used in pigments, pharmaceutica…
Many transition metal compounds are toxic, particularly those of chromium(VI), cadmium, mercury, and lead. Proper handling and disposal are required. Some metals like nickel compounds are carcinogenic.
