  2. Sodium - Wikipedia

    en.wikipedia.org/wiki/Sodium

    Bulk sodium is usually stored in oil or an inert gas. Sodium metal can be easily cut with a knife. It is a good conductor of electricity and heat. Due to having low atomic mass and large atomic radius, sodium is third-least dense of all elemental metals and is one of only three metals that can float on water, the other two being lithium and ...

  3. Standard atomic weight - Wikipedia

    en.wikipedia.org/wiki/Standard_atomic_weight

    The standard atomic weight (A r °(Cu)) for copper is the average, weighted by their natural abundance, and then divided by the atomic mass constant m u. [ 1 ] The standard atomic weight of a chemical element (symbol A r °(E) for element "E") is the weighted arithmetic mean of the relative isotopic masses of all isotopes of that element ...

  4. Isotopes of sodium - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_sodium

    Sodium-23 is an isotope of sodium with an atomic mass of 22.98976928. It is the only stable isotope of sodium and also the only primordial isotope. Because of its abundance, sodium-23 is used in nuclear magnetic resonance in various research fields, including materials science and battery research. [8]

  5. Sodium chloride - Wikipedia

    en.wikipedia.org/wiki/Sodium_chloride

    Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .

  6. Atomic mass - Wikipedia

    en.wikipedia.org/wiki/Atomic_mass

    The atomic mass (relative isotopic mass) is defined as the mass of a single atom, which can only be one isotope (nuclide) at a time, and is not an abundance-weighted average, as in the case of relative atomic mass/atomic weight. The atomic mass or relative isotopic mass of each isotope and nuclide of a chemical element is, therefore, a number ...

    In a trial featuring a mouse model of Alzheimer's, scientists found that inhaling a mixture containing xenon gas helped reduce levels of brain atrophy and neuroinflammation.

  8. Sodium acetate - Wikipedia

    en.wikipedia.org/wiki/Sodium_acetate

    A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.
