Dysprosium Electron Configuration(Explained for Beginners)

Dysprosium is a lanthanide with 66 electrons which is used in laser materials. Let us dig deep into the electronic configuration of Dy.

The electronic configuration of Dy is [Xe]4f¹⁰6s². Electron per shell configuration comes out to be 2,8,18,28,8,2. Dy shows 0, +1, +2, +3, +4 oxidation states.

Dy is a rare earth element that is in the solid phase at STP. In this article, we shall explore the electronic configuration of Dy.

How to write dysprosium electron configuration

The electron configuration of Dy is 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁰5d⁰6s² which is written using the following steps. which is illustrated as follows-

• S orbital can have 2 electrons.
• P orbital can have 6 electrons.
• D orbital can have 10 electrons, and
• F orbital can have 14 electrons.
• Different orbitals can accommodate a certain number of electrons that are filled as per Aufbau’s principle, Pauli’s exclusion principle and Hund’s rule.
