In its elemental state, potassium is alkali metal. It is a solid, silver colored element with atomic mass of 39.0983 amu.
Pure potassium is waxy and soft, and can easily be cut with a knife, but it is also an element that is never found on its own in nature. It is so reactive on its own that it combines with oxygen and water to create potassium super-oxide, potassium hydroxide, hydrogen gas, and heat. The amount of heat can ignite the hydrogen gas. Because of its ability to react, small amounts of potassium are stored and submerged in mineral oil to prevent it.
Potassium was discovered in 1807 by Sir Humphry Davy through electrolysis (a scientific method of passing an electric current through a liquid or ionic solution) of molten caustic potash (another name for potassium hydroxide).
Potassium has few uses, but the uses are very important. Many potassium salts can be used in medical facilities. Potassium carbonate is used as a manufacturer of glass. Potassium hydroxide is used in dish soap and detergents. Potassium chloride is used in pharmaceuticals and saline drips.
All living things need potassium to live: animals, plants, and humans. Some sources of potassium are meats, plants, and dairy products. Fruits and vegetables are the best sources.
