Covalent Radius of Technetium (Tc) - & Sources, Uses ... 2022

Molecules and atoms have a certain 'size or radius', even Technetium. Ok but what is the covalent radius of an atom of Tc?

In the case of Technetium the covalent radius is 1.27 Å. You see, there is a lot of info about Technetium (beyond an atom's radius) that is actually interesting. 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. "Covalent Radius of Technetium (Tc) - & Sources, Uses ..." Materials. 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.
