2022: ☢️ Electron Affinity of Oxygen (O) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Oxygen is defined as the amount of energy released or spent when an electron is added to a neutral atom in the gaseous state to form a negative ion. But what is the electron affinity of an atom of O?

In the case of Oxygen the electron affinity is 141 kilojoules per mole.  There are a lot of cool facts about Oxygen that most people don't know. Check this...

Oxygen Facts

Oxygen Electron Affinity

141 kilojoules per mole

State at 20 °C

Gas

Discovery

Discovered By: Joseph Priestly, Carl Wilhelm Scheele
Year: 1774
Location: England/Sweden

Uses

Used in steel making, welding, and supporting life. Naturally occuring ozone (O3) in the upper atmosphere shields the earth from ultraviolet radiation.

Sources

Obtained primarily from liquid air by fractional distillation. Small amounts are made in the laboratory by electrolysis of water or heating potassium chlorate (KClO3) with manganese dioxide (MnO2) catalyst.

Description

Colorless, odorless, tasteless gas; pale blue liquid. Third most abundant element in the universe. It is the most abundant element in the earth's crust, and makes up almost 21% of the atmosphere.

Atomic Symbol

O

Name Origin

Greek: oxys and genes, (acid former).

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. "Electron Affinity of Oxygen (O) [& Color, 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.
