Nuclear Anatomy: Fundamental Sketch of Yttrium

Yttrium's atomic number is 39, indicating that it has 39 protons in its nucleus. In its neutral state, it also has 39 electrons, which orbit the nucleus in different energy levels or shells. The electron configuration of yttrium characterizes the distribution of these electrons over its energy levels, providing insight into its chemical reactivity and bonding tendencies.


Electron Configuration: Understanding Patterns

To characterize the electron configuration of yttrium, one must follow the principles of the Aufbau principle, Hund's rule, and the Pauli exclusion principle, which govern the arrangement of electrons within an atom.


The electron configuration of yttrium can be explained as follows:


1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶ 4d¹ 5s²


Break it:

  • The first two electrons occupy the 1s orbital.
  • The next eight electrons fill the 2s and 2p orbitals following the Pauli exclusion principle and Hund's rule.
  • Subsequently, the next ten electrons occupy the 3s, 3p and 3d orbitals, completely filling the 3d subshell.
  • After this, the next ten electrons fill the 4s and 4p orbitals.
  • Finally, the last two electrons are accommodated into the 5s orbital, completing the electron configuration of yttrium.
