What are the electron configurations for Nd and Eu?

Interpretation Introduction


The electronic configuration of Nd and Eu has to be written.

Concept introduction:

The electron configuration tells us in which orbitals the electrons for an element are located. Three rules are,

  • Electrons fill orbitals staring with lowest n and moving upwards(Aufbau principle)
  • No two electrons can fill one orbital with the same spin(Pauli Exclusion Principle)
  • For orbitals within the same subshell, the electrons fill each orbital singly before any orbital gets a second electron (Hund’s rule).

Atomic Number is the number of protons in an atom.

  • Atomic Number of neodymium is 60. So the total number of electron is 60. On filling the orbitals in the increasing energy as, 1s22s22p63s23p63d104s24p64d104f45s25p66s2 and since

    [1s22s22p63s23p63d104s24p64d105s25p6]=[Xe]. So the electronic configuration of neodymium is [Xe] 4f46s2.

  • Atomic Number of europium is 63
