The chemical element Potassium's symbol K, comes from which Latin word?
"1736. The exact chemical composition of potassium and sodium compounds, and the status as chemical element of potassium and sodium, was not known then, and thus Antoine Lavoisier did not include the alkali in his list of chemical elements in 1789. For a long time the only significant applications for potash were the production of glass, bleach, soap and gunpowder as potassium nitrate. Potassium soaps from animal fats and vegetable oils were especially prized because they tend to be more water-soluble and of softer texture, and are therefore known as soft soaps. The discovery by Justus Liebig in 1840 that"
"Alum-(K) Alum-(K) is a hydrous potassium aluminium sulfate mineral with formula KAl(SO)·12(HO). It is the mineral form of potassium alum and is referred to as potassium alum in older sources. It is a member of the alum group. It occurs as colorless to white, soft isometric crystals and efflorescence coatings. Rare crystals are octahedral in form if occurring as precipitates from neutral water solution, but cubic in form if the solution is alkaline. It occurs as a precipitate around volcanic fumaroles and solfataras. It also occurs as an alteration in argillaceous sediments or coal beds which contain oxidizing sulfide minerals"
"KREEP KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks. Its most significant feature is somewhat enhanced concentration of a majority of so-called ""incompatible"" elements (those that are concentrated in the liquid phase during magma crystallization) and the heat-producing elements, namely radioactive uranium, thorium, and potassium (due to presence of the radioactive K). The typical composition of KREEP includes about one percent, by mass, of potassium and phosphorus oxides, 20 to 25 parts per million of rubidium,"

"the material was known in ancient times, while for others, the name is a more recent invention. For example, ""He"" is the symbol for helium (New Latin name, not known in ancient Roman times), ""Pb"" for lead (""plumbum"" in Latin), and ""Hg"" for mercury (""hydrargyrum"" in Greek). Some symbols come from other sources, like ""W"" for tungsten (""Wolfram"" in German, not known in Roman times). Temporary symbols assigned to newly or not-yet synthesized elements use 3-letter symbols based on their atomic numbers. For example, ""Uno"" was the temporary symbol for hassium (element 108) which had the temporary name of ""unniloctium""."
"Isotopes of potassium Potassium (K) has 25 known isotopes from K to K, with unconfirmed detection of K. Three isotopes occur naturally: stable K (93.3%) and K (6.7%), and the long-lived radioisotope K (0.012%). Naturally occurring radioactive K decays to stable Ar (10.72% of decays) by electron capture or positron emission (giving it the longest known positron-emitter nuclide half-life). Alternately, and most of the time (89.28%), it decays to stable Ca by beta decay. K has a half-life of 1.248×10 years. The long half life of this primordial radioisotope is caused by a highly spin-forbidden transition: K has a nuclear"

"Gustav Kirchhoff discovered caesium in the mineral water from Dürkheim, Germany. Because of the bright blue lines in the emission spectrum, they derived the name from the Latin word ""caesius"", meaning sky-blue. Caesium was the first element to be discovered with a spectroscope, which had been invented by Bunsen and Kirchhoff only a year previously. To obtain a pure sample of caesium, of mineral water had to be evaporated to yield of concentrated salt solution. The alkaline earth metals were precipitated either as sulfates or oxalates, leaving the alkali metal in the solution. After conversion to the nitrates and extraction"

"K–Ca dating Potassium–calcium dating, abbreviated K–Ca dating, is a radiometric dating method used in geochronology. It is based upon measuring the ratio of a parent isotope of potassium (K) to a daughter isotope of calcium (Ca). This form of radioactive decay is accomplished through beta decay. Calcium is common in many minerals, with Ca being the most abundant naturally occurring isotope of calcium (96.94%), so use of this dating method to determine the ratio of daughter calcium produced from parent potassium is generally not practical. However, in minerals with low calcium content (under 1/50th of the potassium content), this dating"

"K–Ar dating Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar). Potassium is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites. In these materials, the decay product is able to escape the liquid (molten) rock, but starts to accumulate when the rock solidifies (recrystallizes). The amount of argon sublimation that occurs is a function of the purity of the sample, the composition of the mother material,"
