Chromium produces an oxide layer that protects the

Chromium or Cr has a mass of 51.996 g/mol-1 and atomic number 24. Its density is 7.19 g/cm-3, melting point at 1,907 degrees Celsius, and the boiling point at 2,672 degrees Celsius. It contains six isotopes and its electron shell is Ar3d54s1. In 1797, it was discovered by French chemist Nicolas Louis Vauquelin. It was given the name chromium after the Greek word chroma, which translates to “color.”    It is classified as a transition metal and is described as lustrous, brittle, and hard. Its color is a silver-grey that can be highly polished. Chromium doesn’t oxidize in the air but can be unstable in oxygen and produces an oxide layer that protects the metal within. When it is heated it forms a green chromic oxide, which is a type of pigment. It is mined as chromite ore (FeCr2O4). It is mainly mined in South Africa, Zimbabwe, Finland, India, Kazakhstan, and the Philippines.    The main uses of Chromium are in appliances, alloys like stainless steel, chrome plating, and metal ceramics. It was often used to give steel a shiny-silvery look and used in metallurgy to prevent corrosion and also make it look shiny. Some of its other uses are to make synthetic rubies, and chromium oxide (CrO2) to make magnetic tape.    We can or smoke tobacco. E-cigarettes now contain four times more nickel and chromium than traditional cigarettes do. A recent study discovered that chromium Arian Saffari who is the main researcher of this study. There are two main types of chromium, they essential mineral for the body to function normally. Chromium helps our metabolism of insulin and glucose. The way food Chromium is toxic to organisms. Crops have systems that monitor the amount of chromium so its low enough it doesn’t cause any harm. It can accumulate in fish and can cause: respiratory problems, low ability to fight disease, birth defects, infertility, and tumor formation in animals. In an article by Ronald Eisler it states that, the biological compounds and their ionic states. In these studies aquatic plants and marine polychaete worms are the most sensitive groups. Higher levels of Cr+6Some interesting facts about chromium include that it is used to make yellow, red and green pigments. It is the 21st most abundant element in the Earth’s crust. 75% to 85% of chromium is commercially produced and the cost of it pure is 32 dollars per 100 grams.
