Likewise, how did thulium get its name?
Thulium was given its name in honor of the earliest name for Scandanavia, Thule. The element was discovered and named by Swedish chemist Per Teodor Cleve (1840-1905) in 1879. Cleve made his discovery while studying the mineral erbia. The more common chemical name for the group of rare earth elements is the lanthanides.
Similarly, how was Thulium discovered? Thulium was discovered by Swedish chemist Per Teodor Cleve in 1879 by looking for impurities in the oxides of other rare earth elements (this was the same method Carl Gustaf Mosander earlier used to discover some other rare earth elements). Cleve started by removing all of the known contaminants of erbia (Er2O3).
Furthermore, where is thulium found?
The element is never found in nature in pure form but it is found in small quantities in minerals with other rare earths. It is principally extracted from monazite, which contains about 0.007% of thulium and bastnasite (about 0.0008%). The chief ores are in China, US, Brazil, India, Sri lanka and Australia.
Is thulium a metalloid?
The chemical element thulium is classed as a lanthanide and rare earth metal. It was discovered in 1879 by Per Teodor Cleve.
