2022: ☢️ Atomic Radius of Potassium (K) [& State, Uses, Discovery ...

All atoms have a (theoretical) atomic radius, even Potassium. Ok, so what is the atomic radius of an atom of K?

Note: Learn more about the atomic radius here.

In the case of Potassium the atomic radius is 2.77 Å. There are cool facts about Potassium that most don't know about. Let me show you...

Potassium Data

Potassium Atomic Radius

2.77 Å

State at 20 °C

Solid

Uses

Used as potash in making glass & soap. Also as saltpeter, potassium nitrate (KNO3) to make explosives and to color fireworks in mauve. Formerly called kalium (K). Vital to function of nerve and muscle tissures.

Atomic Mass
