  1. Convert (an atom, molecule, or substance) into an ion or ions, typically by removing one or more electrons

  2. Become converted into an ion or ions in this way

  1. become converted into ions
  2. (ionization) the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge); "the ionization of a gas"
  3. (ionization) the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas
  4. Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This is often confused with dissociation (chemistry).
  5. To dissociate atoms or molecules into electrically charged species; to be thus dissociated
  6. (Ionized) is the term for an atom which has lost one or more electrons causing it to become positively charged.
  7. (ionized) State of an atom that has had at least one of its electrons removed.
  8. (ionizes) When a substance breaks into its ionic components.
  9. (ionization) Removal of electrons from an atom, for example, by means of radiation, so that the atom becomes charged.
  10. (Ionization) Generally the dissociation of an atom or molecule into positive or negative ions or electrons. Restrictively, that state of an insulator whereby it facilitates the passage of current due to the presence of charged particles usually induced artificially.
  11. (Ionization) the process by which a neutral atom, or a cluster of such atoms, becomes an ion. This may occur, for instance, by absorbtion of light ("photoionization") or by a collision with a fast particle ("impact ionization"). ...
  12. (ionization) The process by which ions are produced, typically by collisions of electrons, ions, or photons.
  13. (ionization) The process of becoming an ion.
  14. (IONIZATION) The process of separation of a molecule into its electrically charged atoms or parts.
  15. (Ionization) The process by which a neutral atom or molecule acquires a positive or negative charge.
  16. (Ionization) The removing or adding of an electron to a neutral atom, thereby creating an ion.
  17. (ionization) The dissociation or separating of molecules into simpler molecules , atoms, or ions.  Ex. Salt dissolving in water, or the splitting of a water molecule into a H+ and OH- ion.
  18. (IONIZATION) The buildup of ions around the orbiter as it re-enters Earth’s atmosphere. Often an orange-red glow is seen around the Shuttle as the ionization buildup occurs.
  19. (IONIZATION) The presence or absence of standard numbers of electrons on a particular atom or molecule. If the ion is positive, there are fewer than the required number of electrons to form a neutral or "balanced" atom or molecule.
  20. (Ionization) A form of thalassotherapy where seawater has been ionized with negative ions, sprayed and inhaled; aids the upper respiratory tract.
  21. (Ionization) Glossary under revision.
  22. (Ionization) Production of charged particles in a medium. An orbital electron is stripped from a neutral atom, producing an ion pair (a negatively charged electron and a positively charged atom).
  23. (Ionization) The process by which air becomes conductive. It is caused by a tremendous charge difference between two regions of opposite charge, and in the case of lightning it is the process that starts the discharge. ...
  24. (Ionization) The process of producing ions.   In certain chemical reactions ionization occurs by transfer of electrons; for example, sodium atoms and chlorine atoms react to from sodium chloride, which consists of sodium ions (Na^+1) and chloride ions (Cl^-1).
  25. (ionization) The formation of ions, ions are produced when polar compounds are dissolved in a solvent and when a liquid, gas, or solid is caused to lose or gain electrons due to the passage of an electric current.
