Mårtensson, "Core-Level Binding Energies in Metals," J. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. Chromium atom by losing 3 electrons form Cr3+. Lide, (Ed.) in Chemical Rubber Company handbook of chemistry and physics, CRC Press, Boca Raton, Florida, USA, 81st edition, 2000. Its electronic configuration in ground state is 1s2 2s2 2p6 3s2 3p6 4s1 3d5. Ley, Eds., Photoemission in Solids I: General Principles (Springer-Verlag, Berlin) with additional corrections, 1978. Burr, "Reevaluation of X-Ray Atomic Energy Levels," Rev. They are tabulated elsewhere on the WWW (reference 4) and in paper form (reference 5). The data are adapted from references 1-3. I am grateful to Gwyn Williams (Jefferson Laboratory, Virginia, USA) who provided the electron binding energy data. The binding energies are quoted relative to the vacuum level for rare gases and H 2, N 2, O 2, F 2, and Cl 2 molecules relative to the Fermi level for metals and relative to the top of the valence band for semiconductors. All values of electron binding energies are given in eV. It belongs to group 6 of the periodic table having trivial name. It is a steely-gray, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. 1967, 47, 1300.Įlectron binding energies Electron binding energies for chromium.

These elements can be remembered by this line: 50 Cr is suspected of decaying by + + to 50 Ti with a half-life of (more than) 1.8×10 17 years. Chromium metal is valued for its high corrosion resistance and hardness. 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 ). If we are talking about the first 30 elements then the periodic table starts with Hydrogen and ends at Zinc that is an element with atomic number 30. Chromium is a chemical element with the symbol Cr and atomic number 24.
