Thulium is an lanthanide element with atomic number 69.
69 protons, 69 electrons Thulium-169 isotope has 100 neutrons
The atomic mass of 173.04 likely refers to the isotope of the element thulium (Tm), which has an atomic number of 69. Thulium has several isotopes, but the most stable and common isotope is thulium-175, which has an atomic mass of approximately 174.97. However, the value 173.04 does not correspond to a specific isotope but could be a rounded average of thulium's isotopes or a reference to another element in a different context.
Malleable and ductile enough to be cut with a knife, the chemical element Thulium is a fairly soft metal, appearing on the Mohs scale of mineral hardness at 2 to 3.
Well, isn't Thulium a fascinating element? It has 69 protons and 69 electrons. Just imagine those little particles dancing around, creating the unique properties that make Thulium so special. Embrace the beauty of science, my friend!
The sixty-ninth element in the periodic table is thulium (Tm). It is a rare earth metal with atomic number 69 and is named after the ancient city of Thule.
Thulium belongs to the Lanthanide family. Thulium is a silvery metal, so soft it can be cut with a knife. Thulium is stable in air, but reacts slowly with water, and rapidly with acids.
Thulium is named after the ancient name for Scandinavia, Thule. This element was discovered in 1879 by Swedish chemist Per Teodor Cleve.
Thulium has 79 shells.
The symbol for tantalum is Ta.
Thulium, with the chemical symbol Tm, is the chemical element with the atomic number 69.
Thulium--Tm, atomic number 69--is a silvery-white metal.

Thulium is a rare earth metal and does not have a discernible odor in its pure form. It is not known to produce any strong or distinctive smells.
Diamonds are formed from 100% carbon. The elements in Thulium are not conducive to forming diamonds. From the Jefferson Lab Web site: ". . . thulium is primarily obtained through an ion exchange process from monazite sand ((Ce, La, Th, Nd, Y)PO4), a material rich in rare earth elements that can contain as much as 0.007% thulium."
