Here’s Peter Wothers. Potassium – the only element named after a cooking utensil. It was named in 1807 by Humphry Davy after the compound from which he isolated the metal, potash, or potassium hydroxide.In 1814, the Swedish chemist Berzelius advocated the name kalium for potassium, with the chemical symbol K. The English and French-speaking countries adopted Davy and Gay-Lussac/Thénard’s name Potassium, whereas the Germanic countries adopted Gilbert/Klaproth’s name Kalium.The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart.
