Period Number of Promethium (Pm) (& Location, Uses ...

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

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

In the case of Promethium the period number is 6. There is a lot of cool stuff about Promethium that people simply don't know. Let me show you...

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 Promethium (Pm) (& 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.
