Understanding the interactions between vibrational modes

Electronic configuration. 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 6 4f 1 5d 1 6s 2. The electronic configuration of the [math]Ce^ {3+} [/math] ion is therefore: [math] [Xe]4f^ {1} [/math] As the electrons in the 5d and 6s orbitals are the first to be removed, because the energy level of the 4f orbital is less than that of the 5d and 6s orbitals. 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. The concept of electronic configuration has replaced the older concept of valency and valence electrons. It involves the specific arrangement of electrons in shells and sub-shells of Bohr’s atomic model. This model has been widely accepted, and according to it, each atom has shells, which further have subshells.
