![]() ![]() Chromium is a lustrous, hard metal that has a silver-grey colour. In oxygen chromium is unstable and immediately it gives a thin layer of oxide and also protects the metal. Chromium is a chemical element with atomic number 24 and represented by the symbol Cr in the Periodic Table. When we heat chromium it turns into green chromic oxide. The name of the element is derived from the Greek word 'chroma', meaning color, because many of its compounds are brightly coloured. It does not lose lustre when it is in free air. Chromium is silver gray in color and it is highly polished. It is a steel-gray, lustrous, hard metal that takes a high. By the way in other words chromium is a brittle, lustrous and hard metal. Chromium (pronounced /kromim/) is a chemical element which has the symbol Cr and atomic number 24. Advantages of ChromiumÄue to this ability of chromium, these are used in decoration and coating too. ![]() ![]() The melting point is 2180 K while the boiling point is 2944 K. The regular state of chromium is solid in real. This surface is spinel in structure, it is very thick and also prohibits the diffusion of oxygen. When chromium is left in air it makes surface of steel non-reactive by altering the surface of metal through oxidation. Learn about other important chemical elements such as Manganese, Silicon, Carbon which are used together with chromium for alloy making. When it went above 38 degree centigrade, it becomes paramagnetic i.e. Physical Properties of Chromium : Due to all the magnetic properties chromium is known because it is an elemental solid but in spite of this it shows anti-ferromagnetic ordering even in room temperatures. ![]()
