> Cerium is a soft, ductile, silvery-white metallic chemical element with symbol Ce and atomic number 58. X-ray absorption-edge measurements were used to investigate the electronic configuration of cerium in different series of amorphous alloys, namely the Ce-Si alloys and the intermetallic Ce-Ni and Ce-Co alloys. The valence electronic configuration is the arrangement of electrons int the outer most shell of the atom . The electronic configuration of Ce (Z =58) is [Xe] 4f^1 5d^1 6s^2. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. The stability of oxidation state depends mainly on electronic configuration and also on the nature of other combining atom.
