Palladium is a chemical element with the chemical symbol Pd and the atomic number 46. It is a rare transition metal that was discovered in 1804.[1] It is considered to be a Precious metal. Some of its many practical uses include catalysts, electronics, use in blood sugar test strips [2], coins, photography and dental casting.[3] It is most often mined in the Ural Mountains, South Africa, and Ontario.
