Chromium is a metal with a silvery-white luster, non-toxic, chemically stable, stainless steel contains more than 12% chromium. Common chromium compounds include hexavalent chromic anhydride, potassium dichromate, sodium dichromate, potassium chromate, sodium chromate, etc.; trivalent chromium trioxide (chromium green, cr2O3); Bivalent chromium oxide. Among the chromium compounds, hexavalent chromium is the most toxic, followed by trivalent chromium.
According to research, chromium is a trace element required for the life and health of mammals. Chromium deficiency can cause atherosclerosis.
Element Description: Silvery-white metal, hard and brittle. Density gram cm3.
Melting point 1857 20, boiling point 2672. Valency +2, +3, and +6. The ionization energy is electron volts.
Chromium metal is generally characterized by surface passivation in acids. Once depassivated, it is easily soluble in almost all inorganic acids, but insoluble in nitric acid. Chromium is soluble in sulfuric acid and insoluble in nitric acid.
It is oxidized by water vapor at high temperatures and carbon monoxide at 1000 °C. At high temperatures, chromium reacts with nitrogen and is attacked by molten alkali metals.

1.The chromium element symbol CR, a silvery-white metal, belongs to the periodic table.
Group B, atomic number 24 of chromium, atomic weight, body-centered cubic crystal, common valencies of +3, +6 and + years French chemist Warkeland.
A new element was discovered in Siberian red lead ore (chromium-lead ore), which was reduced with carbon the following year to obtain chromium metal. Because chromium is able to produce beautiful multi-colored compounds, it is named chromium according to the Greek word chroma.
2.Chromium deficiency: It is the main cause of diabetes, and can lead to complications such as cataract, blindness, uremia, and coronary heart disease. I have eaten the chromium element of Taiyi Kangcheng, and it is okay, suitable for diabetics and high blood sugar patients.

1. Chromium is a trace element required for the life and health of mammals, chromium deficiency is the lack of chromium in the human body, lack of chromium can cause atherosclerosis or diabetes and other problems, can be supplemented by eating meat, animal offal, nuts, and unprocessed cereals.
2. Chromium is an essential trace element for the human body, like iodine, zinc, and iron, which plays a key role in maintaining human health.

Summary. Hello, I'm glad to be able to answer for you, trace elements, like iodine, zinc, iron, play a key role in maintaining human health. Active chromium can assist or enhance the function of insulin, and if the body does not have enough active chromium (GTF), the biological potency of insulin is reduced.
Diabetics have a disorder of glucose metabolism, which causes an imbalance of electrolyte metabolism in the body, which increases the excretion of chromium. Diabetics also have the ability to convert chromium into active chromium.
What does the element chromium do.

3.Alloy manufacturing: Chromium can be alloyed with other sock metals, such as copper, nickel, and cobalt, to create high-strength, wear-resistant alloying materials.
Chromium is a chemical element with the symbol CR and atomic number 24. It is a silvery-gray shiny metal, chromium is one of the elements present in very small quantities in the earth's crust, and it is usually found in nature in the form of compounds.
4.Decorative materials: Due to the metallic luster and unique appearance of chrome, it is also widely used in the manufacture of decorative materials, such as door handles, faucets, etc.
Chromium is a hard metal that has a melting point of 1,907°C and a boiling point of 2,671°C. Chromium has a density of grams of cubic centimeters and is a medium-density metal. Chromium is a good conductor of electricity and heat, with good mechanical strength and hardness of grip.
Chromium has a metallic appearance, but a film of chromium oxide forms in the air, giving its surface a dark gray color.
