2021: Atomic Volume of Potassium (K) [& Color, Uses, Discovery ...

Atoms have a theoretical atomic volume, even Potassium. Ok, so what is the atomic radius of Potassium?

Note: Learn more about the molar (or atomic) volume here.

In the case of Potassium the atomic volume is 45.46 cm³/mol. There are interesting things about Potassium that people don't know about...

Potassium Data

Potassium Atomic Volume

45.46 cm³/mol

State at 20 °C



Used as potash in making glass & soap. Also as saltpeter, potassium nitrate (KNO3) to make explosives and to color fireworks in mauve. Formerly called kalium (K). Vital to function of nerve and muscle tissures.

Atomic Mass

Found in minerals like carnallite [(KMgCl3).6H2O] & sylvite (potassium chloride, KCL). Pure metal is produced by the reaction of hot potassium chloride and sodium vapors in a special retort.


Soft, waxy, silver-white metal. Eighth most abundant element in the earth's crust (20,900 ppm). Occurs only in compounds.

Are you having trouble understanding the basics of atomic elements? This video will walk you through:
  • What is an element
  • What is a substance
  • What Elements look like
  • How a small number of atoms can be joined and form completely different substances


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. "Atomic Volume of Potassium (K) [& 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.
