Chromium
Chromium is a solid located in period 4 and in group 6B on the periodic table of elements. Which would classify it as a transition metal. Its crystal structure is cubic and its melting point is 1857.0 degrees C (2130.15 K, 3374.6 degrees F). Chromium's Boiling point is at 2672.0 degrees C (2945.15 K, 4841.6 degrees F). Its atomic number is 24 and is a gray solid. All its stable isotopes are Cr-50, Cr-52, Cr-53, Cr-54 and its unstable are Cr-49 and Cr-51. Chromium's atomic mass is 51.9961 amu. Chromium has 24 protons and 24 electrons. It also has 28 neutrons. The atomic structure of chromium is as follows: on the first level there are 2 electrons, on the second level there are 8 electrons, on the third level there are 13 electrons, and on the fourth level there is one electron. Of Course all the protons and neutrons are in the nucleus. In the 18th century an analysis of red lead (PbCrO4, crocoite) from Siberia showe
------------------------------------------------------------------------ Today the element chromium must be separated from its compounds to get it, because it is not found freely in nature. Chromium is a metal that is used in many processes. It is used to form alloys with other metals. Chromium is used to harden steel, and to manufacture stainless steel. It is used in plating to produce a hard, beautiful surface and to prevent corrosion, which most people call chrome. Chrome is mainly used on car trim among other things. Chromium is what gives emeralds their green color, and rubies their red color, so it is used to give glass these colors. It is widely used as a catalyst. Dichromates are oxidizing agents and are used in analysis and in tanning leather. Chromium compounds are used in the textile industry as mordant. It is also used to anodize aluminum by the aircraft and other industry. The Chromium compound chromit
