The chrome, or English (Chromium): is a mineral important chemical elements. It is the general characteristics: it carries the code (Cr), and atomic number (24), and color gray or silver, and has a metallic luster. It was discovered in the eighteenth century, and commonly used in the nineteenth century and beyond, where chromium used in many applications and industries, and most important: the prevention of rust and corrosion and heat for many metals.
Chrome is the first element of Group F, located in the left of the periodic table of elements, and this group is one of the groups metallic elements transition, belongs to this group elements other than chromium, namely: molybdenum (Mo), and tungsten (W), and Saborgiom (Sg). Chrome is fast oxidation of elements in the event of exposure to the open air, where around outer layer consists of chromium oxides that are isolated from the rest of the internal metal air.
Extracted chrome metal of chromite ore found in igneous rocks, as chromium exists slim proportions in many foods, including: meat, liver, eggs, cheese, cereal grind whole: such as wheat, brown rice, corn, and others, chromium is also found in potatoes, and nuts, and others.
It uses chromium metal in many areas, including:
Many of the metals industry and improve the resistance to corrosion and rust, such as: steel industry Negotiable non-oxidants.
Chromium is used in tanning leather, leather tanning: It is addressed to some materials that clear them and remove them damp and stinking hair and readies for use.
Chromium is used in coloring glass, and this is done by some of the salts derived from it.
Chromium is used in the paint and coatings industry by some acids and oxides learned of it, it is also used in the manufacture of some materials used in painting and decoration.
The human body needs to chromium in small quantities ranging from 20 to 100 micrograms daily, and experts recommend greater than 100 micrograms per. Where chromium plays many vital functions in the human body, and those functions:
Chromium increases the effectiveness of insulin in the body, it helps to pass to the inside of cells, as chromium helps insulin to convert carbohydrates and fat into energy. This means that the chrome useful in the prevention of diabetes, and benefit patients who suffer from it.
Chromium helps to regulate cholesterol and glucose in the blood.
Chromium deficiency in the body may lead to many health problems, such as: high cholesterol in the blood, the higher the probability of exposure to heart disease. It can also lead to a deficiency of insulin and the lack of effectiveness of the disordered, leading to the emergence of symptoms of diabetes on the person.
