12/20/2023 0 Comments Element chromium uses![]() The element with the 21st highest abundance in the crust of the Earth is chromium. Chromium also aids in the metabolism of glucose and insulin. They are crucial for the operation of the brain and other bodily processes. It promotes the production of cholesterol and fatty acids. Glassware used in laboratories is cleaned with the substance chromic acid, which also eliminates all traces of organic material.īiologically chromium helps in the breakdown of fats and carbohydrates. Green, purple, red, and orange pigments made of chromium compounds are highly prized. Magnetic tape is produced using chromium (IV) oxide (CrO 2 ).Ĭhrome plating, a thin layer of metal used for decoration and corrosion resistance, contains chromium. Unalloyed chromium's high hardness and corrosion resistance make it a reliable metal for surface coating it is still the most popular metal for sheet coating due to its above-average durability when compared to other coating metals.Ī trace amount of chromium can be found in the crystal lattice structure of valuable gems such as emeralds. When heated, it burns and forms green chromic oxide, which does not tarnish in air.Ĭhromium has a relatively low melting point of 1907 ☌ (3465 ☏) when compared to the majority of transition metals.Ĭhromium has a boiling point of 4,840 ☏ (2,671 ☌). ![]() The physical and chemical properties of chromium are listed below:Ĭhromium is a lustrous steely-grey metal that is brittle and hard. Physical and Chemical Properties of Chromium The average mass of an element in relation to all of its isotopes and their relative abundances is known as its atomic weight though the atomic mass and atomic weight of chromium is 51.996u. Atomic Mass and Atomic Weight of ChromiumĪtomic mass is the measure of the mass of a single atom or isotope. ![]()
