Atomic Radius of Cesium☢️ (Cs) rev. 2022 [& State, Uses, Discovery ...

All atoms have a (theoretical) atomic radius, even Cesium. Ok, so what is the atomic radius of an atom of Cs?

Note: Learn more about the atomic radius here.

In the case of Cesium the atomic radius is 3.34 Å. There are cool facts about Cesium that most don't know about. Let me show you...

Cesium Data

Cesium Atomic Radius

3.34 Å

State at 20 °C

Solid

Uses

Used as a 'getter' to remove air traces in vacuum and cathode-ray tubes. Also used in producing photoelectric devices and atomic clocks. Since it ionizes readily, it is used as an ion rocket motor propellant.

Atomic Mass

132,90543

Learn more about the atomic mass.

Sources

Found in pollucite [(Cs4Al4Si9O26).H2O] and as trace in lepidolite.

Description

Very soft, light gray, ductile metal.

Atomic Symbol

Cs

Name Origin

Latin: coesius (sky blue); for the blue lines of its spectrum.

Atomic Number

55

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. "Atomic Radius of Cesium (Cs) [& State, 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.
