Chromium is a relatively abundant element in Earth’s crust; the free metal is never found in nature. Most ores consist of the mineral chromite , the ideal formula of which is FeCr 2 O 4 . It is widely dispersed in natural deposits, which are usually contaminated with oxygen, magnesium , aluminum , and silica; their chromium content varies from 42 to 56 percent. Chromium is a lightweight blue-silvery white metal. The name chromium comes from the Greek "chroma" and means color.Thanks to its very high corrosion resistance against many different acids and bases as well as hot gases, chromium is a popular material for all types of protective coating.

It can also have an oxidation number of +6 in K2CrO4. There are also less common oxidation states of Cr. Kind of confused when you state this: “If you look at the periodic table, you will find the metals in groups (from one to 16).
