2022: ☢️ Valence Electrons in Thulium (Tm) [& Facts, Color, Discovery ...

A valence electron is an outer shell electron and may participate in the formation of a chemical bond. Ok but how many valence electrons does an atom of Thulium have?

In the case of Thulium the valence electrons is 3. Now let's check the facts about Thulium...

Thulium Overview

Thulium Valence Electrons

3

Atomic Number

Learn more about the atomic number.

Atomic Mass

168,93421

Learn more about the atomic mass.

Atomic Symbol

Tm

State at 20 °C

Solid

Description

Soft, malleable, ductile, silvery metal

Uses

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

Name Origin

From Thule ancient name of Scandinavia.

Sources

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.

Discovery

Discovered By: Per Theodor Cleve
Year: 1879
Location: Sweden

Colored Periodic Table

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

Along with basic atom / element information (like Thulium valence electrons 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).

Citation

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. "Valence Electrons in Thulium (Tm) [& Facts, Color, 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.
