You can effortlessly find every single detail about the elements from this single Interactive Periodic table.How many protons and neutrons does chromium have?Ĭhromium is the first element in the sixth column of the periodic table. Let me tell you how this Interactive Periodic Table will help you in your studies.ġ). Free Gift for you: Interactive Periodic Table Chromium salts are also used in leather tanning.Also the red color of ruby is due to the presence of chromium in it. Chromium is used in preparing pigments.The heat resistance bricks used in furnaces contain chromium in it, due to which the bricks retain strength at higher temperature.Chromium plating is used in coating of car parts, home appliances, etc to give a shiny finish.By electroplating, the thin layer of chromium is applied to other metals. Chromium is used in electroplating of other metals.Stainless steels contain around 11% chromium. Chromium is the most important metal that is used in stainless steel (which is used in manufacturing utensils).Chromium has anti corrosive properties due to which it offers a protective layer to the surface on which chromium is electroplated.Chromium is a transition metal as it has incomplete d-orbitals.But it is always found as a compound with other elements. Chromium is a fairly active metal and so it is not found in a free state.Chemical properties of ChromiumĬhemical properties of chromium are mentioned below. There are many isotopes of chromium, out of which 52Cr is the most abundant (around 84%).The atomic mass of chromium is 51.996 u and has a density of 7.19 g/cm 3.Melting point of chromium is 1907 ☌ and its boiling point is 2671 ☌.Chromium is a strong metal having a silvery metallic lustre.Physical properties of chromium are mentioned below. The physical and chemical properties of chromium element are mentioned below. (Carbon is the first and boron is the second). Chromium element is the 3rd hardest element found on the entire periodic table.The majority of chromium produced in the industries is used in making strong alloys.South Africa is the leading producer of chromium in the world.The majority amount of chromium that is obtained is from the mineral chromite. ![]() The concentration of chromium in earth’s crust is around 100 ppm.Chromium is found in the earth’s crust and it is the 21st most abundant element in the earth’s crust.The name of chromium element is derived from the Greek word “chroma’ (meaning color). ![]() Interesting facts about chromium element are mentioned below. Thus, Chromium has incomplete d-orbitals.Īnd hence, as Chromium has incomplete d-orbitals, it is considered as a transition metal. In order to have the complete d-orbitals, there must be 10 electrons in it.īut in the ground state electronic configuration of chromium, you can see that it has only 5 electrons in d-orbitals. Louis Nicolas Vauquelin in 1794 CAS number īecause, there are only five electrons in the d-orbitals.
