  3. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    The only metal having an ionisation energy higher than some nonmetals (sulfur and selenium) is mercury. [citation needed] Mercury and its compounds have a reputation for toxicity but on a scale of 1 to 10, dimethylmercury ((CH 3) 2 Hg) (abbr. DMM), a volatile colourless liquid, has been described as a 15. It is so dangerous that scientists have ...

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

    Sodium dihydrogen phosphate Sodium hydrogen phosphate Trisodium phosphate. A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms ...

  7. Metalloid - Wikipedia

    en.wikipedia.org/wiki/Metalloid

    A metalloid is a chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals.The word metalloid comes from the Latin metallum ("metal") and the Greek oeides ("resembling in form or appearance"). [1]

  8. Sodium compounds - Wikipedia

    en.wikipedia.org/wiki/Sodium_compounds

    Sodium metal is highly reducing, with the standard reduction potential for the Na + /Na couple being −2.71 volts, [3] though potassium and lithium have even more negative potentials. [4] The thermal, fluidic, chemical, and nuclear properties of molten sodium metal have caused it to be one of the main coolants of choice for the fast breeder ...

  9. Sodium ferrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_ferrate

    Sodium ferrate is a chemical compound with the formula Na 2 FeO 4. It is a sodium salt of ferric acid that is very difficult to obtain. In most iron compounds, the metal has an oxidation state of +2 or +3. Ferric acid, with an oxidation state of +6, is extremely unstable and does not exist under normal conditions.
