2022: ☢️ Atomic Radius of Rubidium (Rb) [& State, Uses, Discovery ...

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

Note: Learn more about the atomic radius here.

In the case of Rubidium the atomic radius is 2.98 Å. There are cool facts about Rubidium that most don't know about. Let me show you...

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 Rubidium (Rb) [& 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.
