Enthalpy of Vaporization of Thulium (Tm) [& Color, Uses, Discovery ...

All atoms need to receive a certain amount of energy (Enthalpy) to change to the gas state, even Thulium. Ok, so what is the enthalpy of vaporization for an atom of Tm?

Note: Learn more about the enthapy of vaporization here.

In the case of Thulium the enthalpy of vaporization is 247.0 Kilojoules per mole. Now let's check some cool facts about Thulium that most don't know about...

Thulium Data

Thulium Enthalpy of Vaporization

247.0 Kilojoules per mole

State at 20 °C



Radioactive thulium is used to power portable x-ray machines, eliminating the need for electrical equipment.

Atomic Mass

Found with other rare earths in the minerals gadolinite, euxenite, xenotime, and monazite. Monazite is often 50% rare earth by weight and 0.007% thulium.


Soft, malleable, ductile, silvery metal

Atomic Symbol


Name Origin

From Thule ancient name of Scandinavia.

Colored Periodic Table

Need an editable periodic table to edit? Maybe add your school logo, work team or anything else to make your paper look cool?

Along with basic atom / element information (like Thulium enthalpy of vaporization and all the other atomic data), it also comes with color coded info about: State (Gas, Liquid or Solid at room temperature), Groups/series details and much more...

How about an incentive to share this post? (You will help other colleagues find this blog)

Download and enjoy this complete and colored periodic table for you to edit and enjoy. It's in an editable excel format or .ods (open).

When you need to include a fact or piece of information in an assignment or essay you should also include where and how you found that piece of information.

That gives credibility to your paper and it is sometimes required in higher education.

To make your life (and citation) easier just copy & paste the information below into your assignment or essay:

Luz, Gelson. "Enthalpy of Vaporization of Thulium (Tm) [& Color, Uses, Discovery ..." Materials. Gelsonluz.com. dd mmmm. yyyy. <URL>

Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. Also replace URL for the actual url of this page (The < and > stay, ok?). This citation format is based on MLA.
