Potassium was discovered in 1807 by Sir Humphry Davy. It was the first metal isolated using electrolysis, marking a major breakthrough in chemistry.
Potassium is abundant in Earth's crust and occurs in minerals such as sylvite and carnallite. It is also dissolved in seawater and is essential for all living organisms.

Potassium compounds are widely used in fertilizers, soaps, glass manufacturing, medicines and industrial chemicals.
Chlorine, Bromine, Oxygen and Sulfur
Potassium reacts violently with water and moist air, so it is stored under mineral oil to prevent dangerous reactions.

Potassium is vital for nerve impulses, muscle contraction, fluid balance and maintaining a healthy heartbeat.
Potassium burns with a beautiful lilac-colored flame, making it easy to identify during flame tests.
Potassium is one of the body's major electrolytes. It helps maintain normal heartbeat, muscle function and communication between nerves and muscles.
Potassium fertilizers improve crop growth, increase disease resistance and help plants withstand drought conditions.
Potassium ions are essential for generating electrical signals in nerves and muscles, allowing the brain and body to communicate rapidly.
Scientists study potassium-ion batteries as a promising alternative to lithium-ion batteries because potassium is more abundant and less expensive.
Potassium is produced inside massive stars through nuclear fusion and later spread across the universe by supernova explosions, becoming part of planets and living organisms.
