2022: ☢️ Electron Configuration of Cobalt (Co) [Complete, Abbreviated, Uses ...

Electrons have a specific form of distribution (or configuration) in every atom, even Cobalt. Some are hard to memorise (or predict), so what is the electron configuration of an atom of Co?

In the case of Cobalt the abbreviated electron configuration is  [Ar] 3d7 4s2. Nevertheless, check the complete configuration and other interesting facts about Cobalt that most people don't know.

Cobalt Overview

Cobalt Complete Electron Configuration
