Chemical element with symbol K and atomic number 19
Potassium is a chemical element; it has symbol K (from Neo-Latin) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. Wikipedia
