Chromium is the hardest metallic facet in the routine table and the only facet that exhibits antiferromagnetic ordering at room temperature, above which that transforms right into a paramagnetic solid. The most common resource of chromium is chromite ore (FeCr2O4). Due to its various vibrant compounds, Chromium was called after the Greek native "chroma." meaning color.
