Enthalpy of Fusion of Neptunium (Np) + Color, Sources, Discovery ... 2022

Energy and heat may change a substance's state from solid to liquid (Fusion). Such energy may be called enthalpy of fusion and it is important even for Neptunium. Ok, so what is the enthalpy of fusion for an atom of Np?

Note: Learn more about the enthalpy of fusion here.

In the case of Neptunium, enthalpy of fusion is 3.20 kilojoules per mole. There are non heat related facts about Neptunium that you might like to know. I'll walk you through...

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. "Enthalpy of Fusion of Neptunium (Np) + Color, Sources, 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.
