2022: ☢️ Ionic Radius of Cobalt (Co) [& Discovery, Color, Uses ...

All atom's ions have an ionic radius, even Cobalt. Ok so what is the ionic radius of a Cobalt ion?

In the case of Cobalt the ionic radius is .65 (+2) Å. Speaking of Cobalt, let me walk you through some interesting details...

Cobalt Facts

Cobalt Ionic Radius
