Introductionpotassium (Latin: Kalium, chemical symbol: K2) is a chemical element with an atomic number of 19. The melting point of potassium, low hardness, more active than sodium, oxidation in the air quickly. The density of potassium is less than that of water and greater than that of ke...
Origin of Name Its symbol “K” is derived from the Latin word for alkali, kalium, but it is commonly called “potash” in English. Occurrence Potassium is the eighth most abundant element in the Earth’s crust, which contains about2.6% potassium, but not in natural elemental form. Potassiu...
