Transition Metal: A metal element that has incompletely filled d orbitals, often exhibiting variable oxidation states and forming colored compounds.
Noble Metal: A metal that is highly resistant to corrosion and oxidation, typically found in elemental form in nature.
Catalytic Converter: A device in a vehicle's exhaust system that uses catalysts to convert toxic pollutants into less harmful substances.
Asymmetric Hydrogenation: A chemical reaction used to add hydrogen to molecules in a way that creates specific stereoisomers, often used in drug synthesis.
