Who discovered potassium and when was potassium discovered?
sir humprhy davy discovered it in 1807 by running an electrical current through some potash (pot-ash) which melted it making potassium Pot ash is made by burning plant leaves pot ash is the old name for Potassium Hydroxide (KOH) Potassium Hydroxide is a Highly Corrosive substance even when dissolved it heats up to about 150-180 degrees , when molten it is extrmely corrosive its fumes can dissolve lung and organic tissue in seconds becarefull Potassium metal, was first isolated by Sir Humphery Davy in 1807AD by the electrolysis of fused potassium hydroxide. Potassium metal is prepared by heating potassium carbonate with charcoal. 2 C + KCO3 ==> 2 K + 3 CO2 Potassium metal was discovered in 1807 in England by Sir Humphry Davy, who derived it from caustic potash (KOH), by the use of electrolysis of the molten salt with the newly discovered voltaic pile. Before the 18th century, no distinction was made between potassium and sodium. Potassium was the first metal that was isolated by electrolysis. Davy extracted sodium by a similar technique, demonstrating the elements to be different. Potassium was found by Sir Humphry Davy in 1807. He got the element from potash, or KOH. It was discovered in the year 1702
Who discovered potassium?
Potassium was discovered in 1807 by British scientist Sir Humphry Davy, who derived it from caustic potash (KOH)where was it discovered and when His first successes came in 1807 with the separation of potassium from molten potash and of sodium from common salt. He described potassium as particles which, when thrown intowater, "skimmed about excitedly with a hissing sound, and soon burned with a lovely lavender light." Dr. John Davy, Humphry's brother, said that Humphry "danced around and was delirious with joy" at his discovery. These results were presented in the Bakerian lecture of November, 1807. Sir Humphrey Davy in 1807

What does lithium mean?
Lithium is the 3rd element in the periodic table. It is an alkali metal (like Sodium and Potassium). It was first given the name "lithos", which in Greek means "stone", as it was discovered in a mineral; as opposed to sodium and potassium, which were discovered in plant tissue. Its name was later standardized as "lithium".
