Give a brief idea about Potassium.
The chemical element potassium has the atomic number 19 and the letter K (which stands for kalium in Neo-Latin). Potassium is a silvery-white metal that may be easily and gently sliced with a knife. Within seconds of exposure, potassium metal quickly combines with air oxygen to produce flaky, white potassium peroxide. It was initially separated from potash, which is made up of plant ashes and from which it gets its name. Potassium is an alkali metal in the periodic table. All alkali metals have a single valence electron in the outer electron shell, which can be removed easily to produce a positive-charged ion called a cation, which interacts with anions to form salts. Only ionic salts include potassium in nature. Potassium interacts vehemently with water, producing enough heat to ignite the hydrogen released during the reaction and producing a flame that is purple in color. It is found in numerous minerals, including orthoclase, a common component of granites and other igneous rocks, and is dissolved in seawater, which contains 0.04% potassium by weight.
