Its name originates with the English word potash (“pot ashes”) and the Arabic word qali (meaning “alkali”). The origin of the symbol K is the Latin word kalium (“alkali”). It is an essential element needed for plant growth. Potassium 41 Chloride (Potassium-41) is a stable (non-radioactive) isotope of Potassium. It is both naturally occurring and produced by fission. Potassium 41 Chloride is one of over 250 stable isotopes produced by American Elements for biological and biomedical labeling, as. Potassium Isotopes, mainly K-40 and K-41, are used to study the impact of potassium on the growth of plants and of the human cardiovascular system. Trace Sciences is your most reliable supplier of stable Potassium Isotopes. Please contact us for other forms of Potassium Isotopes available. Jefferson Lab, U.S. Department of Energy Seventeen isotopes of potassium are known. Ordinary potassium is composed of three isotopes, one of which is 40°K (0.0118%), a radioactive isotope with a half-life of 1.28 x 10 9 years. Los Alamos National Laboratory, U.S. Department of Energy. This isotope makes up one ten thousandth of the potassium found naturally. In terms of atomic weight, it is located between two more stable and far more abundant isotopes (potassium 39 and potassium 41) that make up 93.25% and 6.73% of the Earth total potassium supply respectively.

    …of naturally occurring but radioactive potassium-40 is measured to be 39.964008 amu. Potassium-40 decays predominantly by β-emission to calcium-40, having a measured mass 39.962589. Through Einstein’s equation, energy is equal to mass (m) times velocity of light (c) squared, or E = mc2, the energy release (Q) and the mass…
