  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H 2 O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out ...

  3. Dipolar compound - Wikipedia

    en.wikipedia.org/wiki/Dipolar_compound

    In organic chemistry, a dipolar compound or simply dipole is an electrically neutral molecule carrying a positive and a negative charge in at least one canonical description. In most dipolar compounds the charges are delocalized. [1]

  4. Inductive effect - Wikipedia

    en.wikipedia.org/wiki/Inductive_effect

    A polar bond is a covalent bond in which there is a separation of charge between one end and the other - in other words in which one end is slightly positive and the other slightly negative. Examples include most covalent bonds. The hydrogen-chlorine bond in HCl or the hydrogen-oxygen bonds in water are typical.

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    This transfer causes one atom to assume a net positive charge, and the other to assume a net negative charge. The bond then results from electrostatic attraction between the positive and negatively charged ions. Ionic bonds may be seen as extreme examples of polarization in covalent bonds.

  6. Ionization - Wikipedia

    en.wikipedia.org/wiki/Ionization

    Ionization (or ionisation specifically in Britain, Ireland, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion.

  7. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    A zwitterion is a neutral molecule with positive and negative charges at different locations within that molecule. [ 17 ] Cations and anions are measured by their ionic radius and they differ in relative size: "Cations are small, most of them less than 10 −10 m (10 −8 cm) in radius.

  8. Charge number - Wikipedia

    en.wikipedia.org/wiki/Charge_number

    A chemical charge can be found by using the periodic table. An element's placement on the periodic table indicates whether its chemical charge is negative or positive. Looking at the table, one can see that the positive charges are on the left side of the table and the negative charges are on the right side of the table.

  9. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    Since oxygen is more electronegative than the carbon that is covalently bonded to it, the electrons associated with that bond will be closer to the oxygen than the carbon, creating a partial negative charge (δ −) on the oxygen, and a partial positive charge (δ +) on the carbon. They are not full charges because the electrons are still ...
