2022: ☢️ Electronegativity of Selenium (Se) [& Uses, Discovery, Sources ...

Electronegativity is an important chemical property that tells how an atom of Selenium may atract electrons from other atoms and form a bond. Ok what is the electronegativity of an atom of Se?

In the case of Selenium the electronegativity is 2,55. Now let's dive into some facts about Selenium. I'll walk you through...

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. "Electronegativity of Selenium (Se) [& Uses, Discovery, Sources ..." 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.
