![]() 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. ![]() Protons 24 Neutrons 28 Electrons 24 Symbol Cr Atomic massĢ, 8, 13, 1 Electronic configuration 3d 5 4s 1 Atomic radiusġ89 picometers (van der Waals radius) 1st Ionization energy 6.767 eV ElectronegativityīCC (Body centered cubic) Melting point 2180 K or 1907 ☌ or 3465 ☏ Boiling point 2944 K or 2671 ☌ or 4840 ☏ Density 7.19 g/cm 3 Main isotope 52Cr Who discovered Chromium and when? Silvery metallic color State (at STP) Solid Position in Periodic table Let’s dive right into it! Chromium Element (Cr) Information Appearance So if you want to know anything about Chromium element, then this guide is for you. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Chromium element in Periodic table.) Magnesia, a district of Eastern Thessaly in GreeceĪlumina, from Latin alumen (gen.This is a SUPER easy guide on Chromium element. Symbol Na is derived from Neo-Latin natrium, coined from German Natron, ' natron'.Greek elements hydro- and -gen, ' water-forming'īeryl, a mineral (ultimately from the name of Belur in southern India) īorax, a mineral (from Arabic bawraq, Middle Persian * bōrag) For more detailed information about the origins of element names, see List of chemical element name etymologies. Like the periodic table, the list below organizes the elements by the number of protons in their atoms it can also be organized by other properties, such as atomic weight, density, and electronegativity. It is a tabular arrangement of the elements by their chemical properties that usually uses abbreviated chemical symbols in place of full element names, but the linear list format presented here is also useful. The definitive visualisation of all 118 elements is the periodic table of the elements, whose history along the principles of the periodic law was one of the founding developments of modern chemistry. A chemical element, often simply called an element, is a type of atom which has the same number of protons in its atomic nucleus (i.e., the same atomic number, or Z). This is a list of the 118 chemical elements that have been identified as of 2023. List of the 118 identified chemical elements
