Chromium is most toxic in its +6 oxidation state ( chromium(VI) ) due to its greater ability to enter cells and higher redox potential. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. It is found naturally occuring in rocks, animals, plants, and soil, and is usually mined as chromite ore. Chromium is a chemical element which has the symbol Cr and atomic number 24. Cr Mo periodic table General Name, Symbol, Number chromium, Cr, 24 Chemical series transition metals Group, Period, Block 6, 4, d Appearance silvery metallic Atomic mass 51.9961(6) g/mol Electron configuration Ar 3d54s1 Electronsper shell 2, 8, 13, 1 Physical properties Phase solid Density(near r.t.) 7.15 g/cm Liquid densityat m.p. Chromium is a steely-grey, lustrous, hard and brittle metal 4 which takes a high polish, resists tarnishing, and has a high melting point. 5 Chromium metal is valued for its high corrosion resistance and hardness. It is a steely-grey, lustrous, hard, and brittle transition metal. Hexavalent chromium is key to all materials made from chromium. Chromium is a chemical element with the symbol Cr and atomic number 24. Virtually all chromium ore is processed via hexavalent chromium, specifically the salt sodium dichromate. Chromium is a steely-grey, lustrous, hard and brittle metal 4 which takes a high polish, resists tarnishing, and has a high melting point. Chromium is a chemical element which has the symbol Cr and atomic number 24. Hexavalent chromium ( chromium (VI), Cr (VI), chromium 6) is chromium in any chemical compound that contains the element in the +6 oxidation state (thus hexavalent ).
