Chromium is a chemical element with atomic number 24 and represented by the symbol Cr in the Periodic Table. Chromium is a lustrous, hard metal that has a silver-grey colour. It has a high melting point. The electron configuration of chromium is [Ar]3d 5 4s 1, which can be explained by the stability offered by a half-filled d-orbital.

On 26 July 1761, Johann Gottlob Lehmann found an orange-red mineral in the Beryozovskoye mines in the Ural Mountains which he named Siberian red lead. Though misidentified as a lead compound with selenium and iron components, the mineral was in fact crocoite with a formula of PbCrO4.
