We know where the English name potassium came from, but what about that "K"? The K represents the word Kalium. It is a biologically essential element and also has various. Like sodium (Na) and gold (Au), the symbol is not an abbreviated form of the element's English name. Potassium is an alkali metal and was obtained in pure elemental form in 1807 by Hymphry Davy. Potassium is a little tricky to remember on the periodic table because the symbol is "K". Once isolated, Davy found potassium to be one of the softer metals with a silver color. In fact, potassium is never found by itself in nature. Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite. Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter). Thermochemistry History Uses Geology Biology Binary. Most potassium occurs in the Earth's crust as minerals, such as feldspars and clays. Even though we have been using potash for centuries, Davy officially discovered potassium in 1807.
