What is the Difference Between Chromium and Hexavalent Chromium?Ĭhromium is a chemical element having atomic number 24. A strong oxidizing agent compared to molybdenum and tungsten oxides.The common oxidation states are +3 and +6.Density is about seven times more than the density of water.Exists in the solid phase at standard temperature and pressure.Some chemical properties of chromium are as follows: Furthermore, the major characteristics that cause its high value are high corrosion resistance and hardness. It is important as the main additive for iron alloys such as stainless steel. We can categorize it as a transition metal it is hard but brittle. Further, this element is the first chemical element of group 6 in the periodic table. It is a metal having a silvery metallic appearance. Side by Side Comparison – Chromium vs Hexavalent Chromium in Tabular FormĬhromium is a chemical element having atomic number 24. Thus, this means the hexavalent chromium compound has chromium atoms that have 6 electrons removed from the outermost orbitals. The metal occurs in the +6 oxidation state. The term hexavalent chromium refers to compounds containing chromium. The key difference between chromium and hexavalent chromium is that chromium is a chemical element whereas hexavalent chromium is any compound having chromium in its +6 oxidation state.Ĭhromium is a metal that is very useful in the production of alloys.
