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...

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.Description
