![]() ![]() It is located in Group 6 and it has a melting point of 1907°c and a boiling point of 2671°c being a solid metal at room temperature. Its salts are used as a variety of pigments due to the wide range of colours formed. It may be noted that the configurations of Cr24 and Cu29 (two elements)are anomalous, since Cr24 has 5 electrons (instead of 4) in 3d orbitals and Cu29 has. It does this as a small layer of Chromium oxide forms on the surface preventing further reaction to oxygen. ![]() Chromium is used extensively in the production of stainless steel and other alloys due to its high shine finish and its ability to resist corrosion. ![]() Chromium draws its name from the Greek ‘Chroma’ meaning colour due to its ability to form multiple coloured compounds. To get the complete configuration of an atom, a number of such notations are written one. Chromium is a metal in group VIB of the periodic table with atomic number 24, an atomic weight of 51.996, and a density of 7.19. The ground state electron configuration of ground state gaseous neutral chromium is Ar. have not been rounded to the nearest whole number. 50 Cr is suspected of decaying by + + to 50 Ti with a half-life of (more than) 1.8×10 17 years. The Lanthanides (atomic numbers 58 71) and the Actinides (atomic numbers 90 103). In 1781 he managed to isolate the metal by heating the oxide sample with charcoal. Chromium atoms have 24 electrons and the shell structure is 2.8.13.1. Naturally occurring chromium ( 24 Cr) is composed of four stable isotopes 50 Cr, 52 Cr, 53 Cr, and 54 Cr with 52 Cr being the most abundant (83.789 natural abundance ). It was through his work with the mineral Crocoite that he discovered when it was heated with Potassium carbonate it produced a yellow salt. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. The dichromates are used as oxidizing agents in quantitative analysis, also in tanning leather. Element Chromium (Cr), Group 6, Atomic Number 24, d-block, Mass 51.996. The most important chromates are those of sodium and potassium, the dichromates, and the potassium and ammonium chrome alums. It has the symbol Cr.Ĭhromium was discovered in 1780 by the French chemist Nicolas Louis Vauquelin. Compounds All compounds of chromium are colored. It is a Transition metal and located in Group 6 of the periodic table. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element.
