2022: ☢️ Electron Affinity of Potassium (K) [& Color, Uses, Discovery ...

In chemistry, the electron affinity of an atom of Potassium 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 K?

In the case of Potassium the electron affinity is 48.4 kilojoules per mole.  There are a lot of cool facts about Potassium that most people don't know. Check this...

Potassium Facts

Potassium Electron Affinity

48.4 kilojoules per mole

State at 20 °C

Solid

Discovery

Discovered By: Sir Humphrey Davy
Year: 1807
Location: England

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.

Sources

Found in minerals like carnallite [(KMgCl3).6H2O] & sylvite (potassium chloride, KCL). Pure metal is produced by the reaction of hot potassium chloride and sodium vapors in a special retort.
