  2. Sodium oxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_oxide

    The structure of sodium oxide has been determined by X-ray crystallography.Most alkali metal oxides M 2 O (M = Li, Na, K, Rb) crystallise in the antifluorite structure.In this motif the positions of the anions and cations are reversed relative to their positions in CaF 2, with sodium ions tetrahedrally coordinated to 4 oxide ions and oxide cubically coordinated to 8 sodium ions.

    en.wikipedia.org/wiki/Sodium_compounds

    Sodium atoms have 11 electrons, one more than the stable configuration of the noble gas neon. As a result, sodium usually forms ionic compounds involving the Na + cation. [1] Sodium is a reactive alkali metal and is much more stable in ionic compounds. It can also form intermetallic compounds and organosodium compounds.

  4. Sodium superoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_superoxide

    Sodium superoxide is the inorganic compound with the formula Na O 2. [1] This yellow-orange solid is a salt of the superoxide anion. It is an intermediate in the oxidation of sodium by oxygen.

  5. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The −1 occurs because each carbon is bonded to one hydrogen atom (a less electronegative element), and the − ⁠ 1 / 5 ⁠ because the total ionic charge of −1 is divided among five equivalent carbons. Again this can be described as a resonance hybrid of five equivalent structures, each having four carbons with oxidation state −1 and ...

  6. Partial charge - Wikipedia

    en.wikipedia.org/wiki/Partial_charge

    For example, chemists often choose to look at a small space surrounding the nucleus of an atom: When an electrically neutral atom bonds chemically to another neutral atom that is more electronegative, its electrons are partially drawn away. This leaves the region about that atom's nucleus with a partial positive charge, and it creates a partial ...

  7. NASICON - Wikipedia

    en.wikipedia.org/wiki/NASICON

    NASICON is an acronym for sodium (Na) super ionic conductor, which usually refers to a family of solids with the chemical formula Na 1+x Zr 2 Si x P 3−x O 12, 0 < x < 3. In a broader sense, it is also used for similar compounds where Na, Zr and/or Si are replaced by isovalent elements.

  8. Superoxide - Wikipedia

    en.wikipedia.org/wiki/Superoxide

    In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature. [2]

  9. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    An oxide is a chemical compound in which one or more oxygen atoms combined with another element, such as H 2 O or CO 2. Based on their acid-base characteristics, oxides can be classified into four categories: acidic oxides, basic oxides, and amphoteric oxides and neutral oxides.
