    List of inorganic compounds. ... (only simple oxides, oxyhalides, and related compounds, not hydroxides, carbonates, acids, or other compounds listed elsewhere) P

  3. Lists of molecules - Wikipedia

    en.wikipedia.org/wiki/Lists_of_molecules

    This is an index of lists of molecules (i.e. by year, number of atoms, etc.). Millions of molecules have existed in the universe since before the formation of Earth. Three of them, carbon dioxide, water and oxygen were necessary for the growth of life.

  4. Electron transfer - Wikipedia

    en.wikipedia.org/wiki/Electron_transfer

    Furthermore, theories have been put forward to take into account the effects of vibronic coupling on electron transfer, in particular, the PKS theory of electron transfer. [10] In proteins, ET rates are governed by the bond structures: the electrons, in effect, tunnel through the bonds comprising the chain structure of the proteins. [11]

  5. Electron donor - Wikipedia

    en.wikipedia.org/wiki/Electron_donor

    The electron donating power of a donor molecule is measured by its ionization potential, which is the energy required to remove an electron from the highest occupied molecular orbital . The overall energy balance (ΔE), i.e., energy gained or lost, in an electron donor-acceptor transfer is determined by the difference between the acceptor's ...

  6. Inorganic chemistry - Wikipedia

    en.wikipedia.org/wiki/Inorganic_chemistry

    Inorganic compounds exhibit a range of bonding properties. Some are ionic compounds, consisting of very simple cations and anions joined by ionic bonding.Examples of salts (which are ionic compounds) are magnesium chloride MgCl 2, which consists of magnesium cations Mg 2+ and chloride anions Cl −; or sodium hydroxide NaOH, which consists of sodium cations Na + and hydroxide anions OH −.

  7. Inorganic compound - Wikipedia

    en.wikipedia.org/wiki/Inorganic_compound

    An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsā  ‍ — ‍ that is, a compound that is not an organic compound. [1] [2] The study of inorganic compounds is a subfield of chemistry known as inorganic chemistry.

  8. Octet rule - Wikipedia

    en.wikipedia.org/wiki/Octet_rule

    Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet. The energy required to transfer an electron from a sodium atom to a chlorine atom (the difference of the 1st ionization energy of sodium and the electron affinity of chlorine) is small: +495.8 − 349 ...

  9. Electron configurations of the elements (data page) - Wikipedia

    Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms. Electron configurations of elements beyond hassium (element 108) have never been measured; predictions are used below.
