Chromium
Chromium was discovered in France in 1797. A man named Louis-Nicholas Vauquelin discovered chromium while experimenting with a material known as Siberian red lead. The name Chromium comes from the Greek word "chroma" meaning "color." Chromium got this name because of the many different colors in the element. This element is hard, metallic and shiny. Chromium doesn't tarnish.
Chromium is a metal element. Chromium's symbol is "Cr" and has an atomic number of 24. This metal is the first element in group 6. It has an Atomic mass of 52.0. Chromium has 4 known isotopes. Chromium is a "transitional metal." The other family members in period 6 are molybdenum (Mo), tungsten (W), and seaborgium (Sg). All elements in group 6 are transitional metals.

Chromium reacts directly with fluorine to create chromium fluoride (CrF6). "Chromium metal reacts with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2, and iodine, I2, to form the corresponding trihalides chromium(III) fluoride, CrF3, chromium(III) chloride, CrCl3, chromium(III) bromide, CrBr3, or chromium(III) iodide, CrI3 (webelements).” Chromium does not react with air or water. Chromium dissolves when it reacts with hydrobromic acid. Chromium and its family are all not very reactive.
Chromium is used in a lot of different ways in our life. One way is, it is used to harden steel, and make stainless steel. Our everyday tools and counters are made of stainless steel. Our bodies need trace amounts of chromium to survive. Another way chromium is useful is it is used to make expensive gems like emeralds. Chromium is also found in paints and dyes used for fabrics. It is also used to make electric tape. Without Chromium, we wouldn’t be able to function properly and we wouldn’t have our everyday house hold
