Palladium (Pd) is a silver-white metal that has the atomic number 46 in the periodic table. It is a Transition metal and located in Group 10 of the periodic table. It has the symbol Pd.

Palladium is a rare metal that is lustrous and silvery white. It is a platinum metal which can be beaten into a think leaf like gold. It is strongly resistant to corrosion. Palladium like Rhodium is used in catalytic convertors of cars and is also used as a catalyst in the cracking of petrol fractions. Palladium is a free metal that is found in the earths crust. It was discovered in 1803 by William Wollaston. He examined residues left over from platinum reactions and upon heating extracted Palladium Cyanide. Its name stems from the word ‘Pallas’ the Greek Goddess of wisdom. It is located in Group 10 as a Transition metal. It has a melting point of 1555°c and a boiling point of 2960°c.
