transition metals
D-block periodic elements
Transition metals are metallic elements occupying the central block of the periodic table, characterized by partially filled d electron orbitals.
This group includes familiar metals like iron, copper, gold, and silver.
They typically form colored compounds, exhibit multiple oxidation states, and serve as catalysts in chemical reactions.
Transition metals are essential in industrial processes and biological systems alike.
