His method of production of this Salt of Alkali is pretty similar to that described by Boerhaave with both processes actually yielding an impure mixture of what we would now call potassium and sodium carbonate; the wood ash method yielding more potassium carbonate, potash, the salty herbs giving more sodium carbonate, soda. Low = substitution is possible with little or no economic and/or performance impact. This means the atomic number of potassium is 19 and each potassium atom has 19 protons. Period For keen lexicographers apparently the Persian word in question Zarnikh was subsequently borrowed by the Greeks for their word arsenikon which means masculine or potent. Potassium has two stable isotopes, with 20 or 22 neutrons. eds. Although Potassium only has two stable isotopes (K-39 and K-41), the long-lived radioisotope K-40 is often also regarded as a stable isotope.

Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart. [102] In 2005, about 93% of world potassium production was consumed by the fertilizer industry. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system. Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. It was first isolated from potash, the ashes of plants, from which its name derives. Potassium is so reactive , it will even react and burn a hole through ice. These values were determined using several different methods. These agents deprive the fire of oxygen and cool the potassium metal. Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash.
