2022: ☢️ Electron Affinity of Cobalt (Co) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Cobalt 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 Co?

In the case of Cobalt the electron affinity is 15.7 kilojoules per mole.  There are a lot of cool facts about Cobalt that most people don't know. Check this...

Cobalt Facts

Cobalt Electron Affinity

15.7 kilojoules per mole

State at 20 °C

Solid

Discovery

Discovered By: George Brandt
Year: 1739
Location: Sweden

Uses

Used in many hard alloys; for magnets, ceramics and special glasses. Remains hard up to 982°C. Radioactive cobalt-60 is used in cancer therapy.

Sources

Occurs in compounds with arsenic, oxygen and sulfur as in cobaltine (CoAsS) and linneite (Co3S4). Pure cobalt is obtained as a byproduct of refining nickel, copper and iron.
