What is Potassium? Origin / Meaning of the name Potassium The name was coined by Sir Humphry Davy and originates from the Medieval Latin word kalium (hence the symbol 'K') for potash. This is because the substance was originally obtained by soaking wood ashes in water and evaporating the mixture in an iron pot. What is Potassium? Periodic Table Group and Classification of the Potassium Element Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Potassium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table. An Element classified as an Alkali Metal is a very reactive metal that does not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals. For additional facts and information refer to Potassium Properties. What is Potassium? Occurrence of the Potassium Element Potassium is a constituent of many common rocks and minerals, and is therefore a rather abundant element, though not so abundant as Sodium. Feldspar, which occurs both by itself and as a constituent of granite, contains considerable potassium. The element is a constituent of all clay and of mica and also occurs in very large deposits at Stassfurt, Germany, in the form of the chloride and sulphate, associated with compounds of sodium and Magnesium. In small quantities it is found as nitrate and in many other forms. Refer to Potassium Reaction for its reaction to Water, Oxygen & Acids. Potassium makes up about 2.4% of the weight of the Earth's crust Seventh most abundant element Found in ancient lakes and seas Mined in USA, Germany & New Mexico Density less than that of water Rapidly oxidises in air Abundances of the element in different environments % in Universe 0.0003% % in Sun 0.0004% % in Meteorites 0.07% % in Earth's Crust 1.5% % in Oceans 0.042% % in Humans 0.2% Medical Uses of Potassium - Health and Treatments Interesting information is contained in the following table of Medical Uses of Potassium, Health and Treatments.
