Chromium (Cr) is a chemical element found at number 24 on the periodic table. It is a hard, lustrous gray transition metal used in plating processes and the production of stainless steel.
Chromium is generally found in nature in the mineral chromite (FeO - Cr2O3), but can also be found in crocoite (PbCrO4). It is also an essential mineral for life; a deficiency will lead to a reduction in glucose tolerance, as several chromium (III) compounds have been found to enhance the effectiveness of insulin. However, some chromates are hazardous to one's health when injested/inhaled.
