Palladium is a precious metal widely used in catalytic converters, electronics, and hydrogen purification.

About Palladium

Widely deployed in automotive catalytic converters, electronics, and hydrogen purification, palladium (Pd) is element 46 and a leading member of the platinum group. It sits in group 10 of period 5 in the d-block and is notable for the filled-shell electron configuration [Kr] 4d¹⁰, with an atomic mass of 106.42 and a Pauling electronegativity of 2.2. The metal has a remarkable capacity to absorb hydrogen, which underlies its role in purifying and storing the gas. A soft, ductile, silvery-white precious metal, palladium is solid at standard conditions and resists tarnish and corrosion, qualities that sustain its value in both industry and jewelry.
