Uncovering the Versatile Properties and Uses of Thulium

Thulium is a rare earth element and a member of the lanthanide series. It is noted for its unique electronic configuration, which makes it an interesting subject of study in the field of chemistry.

This article aims to provide an overview of the electronic configuration of Thulium and its properties.

Electronic Configuration of Thulium

Thulium has an atomic number of 69, which means it has 69 electrons orbiting around the nucleus. These electrons occupy different energy levels or shells, with each shell having a maximum number of electrons it can hold.

For an atom of Thulium, the electronic configuration can be represented as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f13 5s2. Aufbau principle, Pauli’s exclusion principle, and Hunds rule of Maximum Multiplicity are the guiding principles that dictate the electronic configuration of Thulium.

The Aufbau principle states that when building up the electronic configuration of an atom, each electron goes into the lowest available energy level or shell. Hence, for Thulium, the two electrons in the 1s sub-shell are filled, followed by the 2s sub-shell, 2p sub-shell, until the 4f sub-shell.

Pauli’s exclusion principle states that two electrons in an atom cannot have the same set of four quantum numbers. This means that each orbital (sub-shell) can hold a maximum of two electrons with opposite spins.

Hund’s rule of Maximum Multiplicity states that for sub-shells with more than one orbital, such as the 4f sub-shell of Thulium, electrons distribute themselves with similar spins in different orbitals before pairing up with opposite spins. Based on these principles, Thulium’s electronic configuration can be represented in an orbital diagram, which shows all the sub-shells occupied by electrons in the atom.
