Potassium-is the chemical element with the symbol K (from Neo-Latin kalium) and nuclear number 19. Elemental special K is a soft silvery-white nucleotide metal that oxidizes promptly in air and is very oxidizable with water, generating sufficient heat to ignite the hydrogen emitted in the reaction.
Because potassium and atomic number 11 are chemically very similar, it took a bulky time before their salts were differentiated. The existence of multiple elements in their salts was suspect from 1702, and this was proven in 1807 when potassium and sodium were individually discriminate from different salts by electrolysis. Potassium in nature occurs only when in ionic salts. As such, it is found dissolved in seawater (which is 0.04% potassium by weight), and is part of many minerals.
more or less industrial chemical applications of potassium employ the relatively amply solubility in water of potassium compounds, such as potassium soaps. Potassium metal has only a a few(prenominal) special applications, being replaced in most chemical reactions with sodium metal.
Potassium ions are necessary for the function of all sustentation cells. Potassium ion diffusion is a key mechanism in nerve transmission, and potassium depletion in animals, including humans, results in various cardiac dysfunctions.
Potassium is found in especially high concentrations inwardly plant cells, and in a mixed diet, it is mostly grueling in fruits. The high concentration of potassium in plants, associated with comparatively low amounts of sodium there, resulted in potassiums being first stranded from potash, the ashes of plants, giving the element its name. Heavy crop production rapidly depletes soils of potassium, and agricultural fertilizers consume 95% of global potassium chemical production.

* Physical
Potassium atoms have 19 electrons, which is one more than the passing stable configuration of argon. A potassium atom is then much more likely to lose the extra electron than to gain one; however,...If you want to get a blanket(a) essay, order it on our website: Orderessay
