Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
Fertilizer use is the main driver behind potash consumption, especially for its use in fertilizing crops that contribute to high-protein diets. [22]: 23 As of at least 2010, more than 95% of potash is mined for use in agricultural purposes. [22]: 24 Elemental potassium does not occur in nature because it reacts violently with water. [34]
The sodium–potassium pump a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...
Potassium cyanide is a compound with the formula KCN. It is a colorless salt, similar in appearance to sugar , that is highly soluble in water. Most KCN is used in gold mining , organic synthesis , and electroplating .
Potassium chloride, also known as potassium salt, is used as a medication to treat and prevent low blood potassium. [2] Low blood potassium may occur due to vomiting, diarrhea, or certain medications. [3] The concentrated version should be diluted before use. [2] It is given by slow injection into a vein or by mouth. [4]

Potassium iodide is a component in the electrolyte of dye sensitised solar cells (DSSC) along with iodine. Potassium iodide finds its most important applications in organic synthesis mainly in the preparation of aryl iodides in the Sandmeyer reaction, starting from aryl amines. Aryl iodides are in turn used to attach aryl groups to other ...
