Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Thulium is an easily workable metal with a silvery-gray luster. When oxidized, it forms a pale yellow oxide.
Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series, and as such, is a rare earth element. Thulium was discovered in 1879 by Swedish chemist Per Teodor Cleve.
The melting point of Thulium is 1545 degrees Celsius. This means that it will liquefy when heated to this temperature, and remain a liquid until cooled below this point.
The boiling point of Thulium is 1950 degrees Celsius.
Thulium is found in a variety of minerals, including euxenite, gadolinite, and monazite. It is also found in small quantities in the Earth’s crust.
Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Thulium is classified as a rare earth element.
Thulium has very few applications due to its scarcity and high cost. One of its primary uses is in portable x-ray devices, where it is used as an x-ray source. Another use for thulium is in lasers for medical and dental procedures, as well as for industrial applications. A minor use for thulium is in glass making, where it can be used to create glasses with a high refractive index.
The physical properties of thulium are largely influenced by its position in the lanthanide series. As a result, thulium has many similarities to both europium and ytterbium. Thulium is a soft, silvery-white metal that is relatively ductile and malleable. When exposed to air, thulium quickly oxidizes and forms a yellowish oxide film on its surface.
Thulium has a few key uses that make it a valuable resource. For example, thulium is used in portable X-ray machines and can also be used as a dopant in fiber optics and lasers. Additionally, thulium is being studied for its potential use in nuclear fusion reactors.
In conclusion, thulium is a rare earth element with a variety of potential applications. While it is not yet widely used, its unique properties make it an intriguing option for many different fields. From medical imaging to pollution control, thulium could potentially have a big impact in the years to come.
We guarantee you’ll find the right tutor, or we’ll cover the first hour of your lesson.
Club Z! has connected me with a tutor through their online platform! This was exactly the one-on-one attention I needed for my math exam. I was very pleased with the sessions and ClubZ’s online tutoring interface.
My son was suffering from low confidence in his educational abilities. I was in need of help and quick. Club Z! assigned Charlotte (our tutor) and we love her! My son’s grades went from D’s to A’s and B’s.
I’ve been using Club Z’s online classrooms to receive some help and tutoring for 2 of my college classes. I must say that I am very impressed by the functionality and ease of use of their online App. Working online with my tutor has been a piece of cake. Thanks Z.
Jonathan is doing really well in all of his classes this semester, 5 A’s & 2 B’s (he has a computer essentials class instead of PLC). In his Algebra class that Nathan is helping him with he has an A+.
Sarah is very positive, enthusiastic and encourages my daughter to do better each time she comes. My daughter’s grade has improved, we are very grateful for Sarah and that she is tutoring our daughter. Way to go ClubZ!
