Cerium is especially interesting because of its variable electronic structure. The energy of the inner 4f level is nearly the same as that of the outer (valence) electrons, and only small amounts of energy are required to change the relative occupancy of these electronic levels. The electronic configuration of Ce (Z =58) is [Xe] 4f^1 5d^1 6s^2. When cerium is doped into a crystal, its ground state split into 2 F 5/2 and 2 F 7/2 sublevels and its excited state split into five components. Please give the electron configurations for the following elements: 1. Log in. The atomic number of cerium (Ce) is 58. Cerium (Ce) is atomic number 58 on the periodic table. (b) NO, 3. 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 atomic radius or Bohr radius of cerium is 185 pm. 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f1 5d1 6s2. 2. Cerium Gadolinium Lutetium in Periodic Table. Q1 Why cerium(58) electronic configuration is written as 4f1 5d1 6s2 instead of 4f2 5d0 6s2 and why after cesium i e praseodymium(59) is written as 4f3 5d0 6s2, if they had started filling 5d first - Chemistry - Classification of Elements and Periodicity in Properties The energy of the inner 4f level is nearly the same as that of the outer (valence) electrons, and only small amounts of energy are required to change the relative occupancy of these electronic levels.
