Thulium is a chemical element with symbol Tm and atomic number 69, part of the lanthanide series on the periodic table. Discovered in 1879 by Swedish chemist Per Teodor Cleve, it’s named after Thule, a mythical region in Scandinavia. Though termed „rare,” thulium is more abundant than silver in the Earth’s crust. It’s usually mined from monazite sand, where it coexists with other rare earth elements.
Thulium is silver-gray, soft enough to be cut with a knife, and has a bright luster. Stable in air and resistant to corrosion, it has one naturally occurring isotope, Tm-169, which is not radioactive. However, radioactive isotopes can be created in nuclear reactors for medical imaging and cancer treatment as it emits X-rays.
In technology, thulium is used in lasers for medical and dental procedures, and in solid-state electronics. Despite these uses, its rarity makes it expensive and limits its widespread application. Thulium also finds a role in research due to its unique properties among the rare earth elements.
The exploration of minerals and stones has always been a fascinating journey for scientists, geologists, and enthusiasts alike. Among the plethora of elements that the Earth’s crust holds, rare earth elements (REEs) have garnered significant attention due to their unique properties and applications.
