Thulium, Named After the Mythical Northern Land of Thule from Greek Mythology
Introduction In 1879, Swedish chemist P. T. Cleve isolated pale green thulium oxide from erbium ores and named it “Thulia” […]

Previous articles mentioned the discovery of erbium oxide by scientist Mosander, leading not only to the separation of ytterbium (Yb)
The Naming Debate of the Youngest Sibling of Ytterby Village’s triplets—Ytterbium
Ytterbium is a rare earth element with the chemical symbol Yb. First isolated in 1878 from gadolinite, its name comes from the village of Ytterby in Sweden, where the mineral was discovered. It has multiple stable and radioactive isotopes and is primarily used in laser technology, alloy strengthening, fiber optic communications, medical imaging, and nuclear medicine. Its properties make it useful in aviation, chemicals, electronics, geophysical monitoring, and it holds potential in high-density explosives and optical clocks.
“Erbium” seems to have a knack for separation, as it has given rise to several rare earth elements
In a previous article, we mentioned the rare earth element “Terbium.” Its sibling elements, discovered in the same year, include
The Rare Earth Triplets—Terbium, the Unfortunate Victim
Previously, we discussed how “Yttrium” was discovered in a mine near the village of Ytterby in Sweden. Interestingly, there are

When discussing rare earth elements, we cannot overlook the large group of lanthanides, one of the most important categories in
Scandium’s Connection to Lighting
The previous article mentioned that the rocks brought back by Apollo contained the superconducting element Yttrium, in fact there are quite a number of other rare earth elements on the moon as well, such as the element Scandium which is quite rare…
