Chromic acid is used in chromium plating, ceramics, and colored glass. Here are 10 fun and interesting facts about the element chromium, a shiny blue-gray transition metal. have not been rounded to the nearest whole number. Chromium compounds can also be used as industrial catalysts too. The Lanthanides (atomic numbers 58 71) and the Actinides (atomic numbers 90 103). Nichrome, an alloy with nickel and chrome, is used for heating units because of its high heat resistance. Chromite is mainly used as a refractory, because of its heat stability. The ground state electron configuration of ground state gaseous neutral chromium is Ar. Chromium is also alloyed with nickel and iron, as well as used as a pigment for glass, paint, glazes. Chromium atoms have 24 electrons and the shell structure is 2.8.13.1. Ferrochromium, a compound with chromium and iron, is mostly used in the production of stainless steel. Uses of ChromiumĬhromium, hard, steel-gray metal with the symbol Cr, is mainly used in stainless steel production. There is a large number of chromium plated parts produced to be used in automobile, construction, and other industries. The most popular industrial use of chromium is producing mirrors and stainless steel. Nicolas-Louis Vauquelin Related Topics: chemical element transition metal chromium processing See all related content chromium (Cr), chemical element of Group 6 (VIb) of the periodic table, a hard steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance. But in large doses chromium is very toxic. In very small doses, chromium is vital for living organisms as it helps glucose digestion. This chemical element can be mainly found in chromites, and it is used as an element of alloys like the one with steel, to produce very strong metal. It has got its name after the Greek word ‘chroma’ which means color. 1999‑2023 - All Rights Reserved.Chromium is a metal of a silvery-blue color and quite toxic.

The elements marked with an asterisk have no stable nuclides. The values shown here are based on the IUPAC Commission determinations ( Pure Appl. For relative abundances of isotopes in nature, see reference on Atomic Weights and Isotopic Compositions.Ītomic weight: Atomic weight values represent weighted average of the masses of all naturally occurring isotopes of an element. The abundance of each isotope depends on the source of materials. For example, the two common isotopes of carbon, 12C and 13C, have 6 and 7 neutrons, respectively. Elements have more than one isotope with varying numbers of neutrons. The isotope of an element is defined by the sum of the number of protons and neutrons in its nucleus. Isotope: Atoms of the same element with the same atomic number, but a different number of neutrons. Thus, each proton and neutron has a mass of about 1 amu. This isotope of carbon has 6 protons and 6 neutrons. Atomic mass is measured in Atomic Mass Units (amu), which are scaled relative to carbon, 12C, that is taken as a standard element with an atomic mass of 12. Each element is uniquely defined by its atomic number.Ītomic mass: The mass of an atom is primarily determined by the number of protons and neutrons in its nucleus. Boiling pointĪtomic number: The number of protons in an atom.
