It is the twenty-fourth element in the periodic table, its sign being Cr and its atomic mass 51.9961. The term that it bears by name, is a derivative of the Greek "chroma", a word that, translated into Spanish, means "color" , due to the colors that can be noticed, they have their components. It is a metal that is highly resistant to corrosion, although its structure is slightly brittle, it is classified as transitional and has a bright grayish color.
It is a widely used material in metallurgy. Some of their properties are used as ingredients for colorants and paints, since, as mentioned before, they have different colors in their extension.
During the year 1961, the scientist Johann Gottlob Lehmann, obtained a mineral that had a distinctive orange color (crocoite). Years later, Louis Nicolas Vauquelin, was able to create, from a sample of crocoite, chromium oxide. Likewise, after some years in which the Vauquelin technique was perfected, it was used as a pigment in coloring mixtures, in addition to being used as an additive for steel. According to scientific studies, it is known that chromium is an essential element in the environment, however, it is not known exactly what role they play.
It can be a factor that gives the condition of "glucose tolerant" to a being, because if it is absent in the body it produces intolerance to the aforementioned component. It is not considered harmful to health, as it is essential, although in canned concentrations it can be toxic to humans. It can cause irritation to the eyes, skin and mucosa, as well as being carcinogenic in non-lethal doses. According to the WHO, there is 0.05mg of chromium in drinking water.
