  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). In chemistry , polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment , with a negatively charged end and a positively charged end.

  3. Potassium sulfate - Wikipedia

    en.wikipedia.org/wiki/Potassium_sulfate

    Potassium sulfate (US) or potassium sulphate (UK), also called sulphate of potash (SOP), arcanite, or archaically potash of sulfur, is the inorganic compound with formula K 2 SO 4, a white water-soluble solid. It is commonly used in fertilizers, providing both potassium and sulfur.

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    However when counting electrons, negative ions should have extra electrons placed in their Lewis structures; positive ions should have fewer electrons than an uncharged molecule. When the Lewis structure of an ion is written, the entire structure is placed in brackets, and the charge is written as a superscript on the upper right, outside the ...

  5. Electronegativity - Wikipedia

    en.wikipedia.org/wiki/Electronegativity

    Electrostatic potential map of a water molecule, where the oxygen atom has a more negative charge (red) than the positive (blue) hydrogen atoms. Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1]

  6. Ammonium - Wikipedia

    en.wikipedia.org/wiki/Ammonium

    Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).

  7. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    The orbital wave functions are positive in the red regions and negative in the blue. The right column shows virtual MO's which are empty in the ground state, but may be occupied in excited states. In chemistry , a molecular orbital ( / ɒr b ə d l / ) is a mathematical function describing the location and wave-like behavior of an electron in a ...

  9. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    Potassium sulfate/magnesium sulfate fertilizer. Potassium ions are an essential component of plant nutrition and are found in most soil types. [14] They are used as a fertilizer in agriculture, horticulture, and hydroponic culture in the form of chloride (KCl), sulfate (K 2 SO 4), or nitrate (KNO 3), representing the 'K' in 'NPK'.
