  2. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [9] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.

  3. Potassium-40 - Wikipedia

    en.wikipedia.org/wiki/Potassium-40

    Potassium-40 is especially important in potassium–argon (K–Ar) dating. Argon is a gas that does not ordinarily combine with other elements. So, when a mineral forms – whether from molten rock , or from substances dissolved in water – it will be initially argon-free, even if there is some argon in the liquid.

  4. Chain-melted state - Wikipedia

    en.wikipedia.org/wiki/Chain-melted_state

    Described more formally, the potassium metal developed two internal structures, a chain-like lattice that dissolved, and a stronger Bravais lattice that remained in a solid state. This is a type of host–guest chemistry where, in this case, the host lattice of metal atoms remains solid while some of the material binds weakly and resembles a ...

    The sodium–potassium pump a critical enzyme for regulating sodium and potassium levels in cells. Potassium is the main intracellular ion for all types of cells, while having a major role in maintenance of fluid and electrolyte balance. [1] [2] Potassium is necessary for the function of all living cells and is thus present in all plant and ...

  7. Isotopes of potassium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_potassium

    All other potassium isotopes have half-lives under a day, most under a minute. The least stable is 31 K, a three-proton emitter discovered in 2019; its half-life was measured to be shorter than 10 picoseconds. [5] [6] Stable potassium isotopes have been used for several nutrient cycling studies since potassium is a macronutrient required for ...
