Oxidation States of Protactinium (Pa) [& Origin, Uses, Discovery ... 2022

Atoms may form different ions and have different oxidation states, even Protactinium. Ok, so what are the common oxidation states for an atom of Pa?

Note: Learn more about the oxidation states here.

In the case of Protactinium the most common oxidation states is ( (5),4). There are also cool facts about Protactinium that most don't know about. Let me show you...

  • 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. "Oxidation States of Protactinium (Pa) [& Origin, 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.
