Period Number of Thorium (Th) (& Location, Uses ...

All atoms have a period number assigned, even Thorium. Ok but how do we know what is the period name for an atom of Th?

If we know the symbol, let's say Th, we may then open any periodic table and search for Thorium. Any decent periodic table should have the period numbers when you scroll left starting from the element you found.

In the case of Thorium the period number is 7. There is a lot of cool stuff about Thorium that people simply don't know. Let me show you...

solid

Description

Heavy, gray, soft, malleable, ductile, radioactive metal.

Atomic Symbol

Th

Name Origin

Named for Thor, Norse god of thunder.

Sources

Found in various minerals like monazite and thorite.

Uses

Used in making strong alloys. Also in ultraviolet photoelectric cells. It is a common ingredient in high-quality lenses. Bombarded with neutrons make uranium-233, a nuclear fuel.

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 Thorium period number 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. "Period Number of Thorium (Th) (& Location, Uses ..." 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.
