  2. Self-ionization of water - Wikipedia

    en.wikipedia.org/wiki/Self-ionization_of_water

    The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.

  3. Isotope-ratio mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Isotope-ratio_mass...

    Oxygen isotope ratios are measured relative the standard, V-SMOW (Vienna Standard Mean Ocean Water). Isotope-ratio mass spectrometer used to measure stable isotope ratios, with gas bench in foreground. It is critical that the sample be processed before entering the mass spectrometer so that only a single chemical species enters at a given time.

  4. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Forming an ionic bond, Li and F become Li + and F − ions. An ion (/ ˈ aɪ. ɒ n,-ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge ...

  5. Ionic bonding - Wikipedia

    en.wikipedia.org/wiki/Ionic_bonding

    Larger negative ions are more easily polarized, but the effect is usually important only when positive ions with charges of 3+ (e.g., Al 3+) are involved. However, 2+ ions (Be 2+ ) or even 1+ (Li + ) show some polarizing power because their sizes are so small (e.g., LiI is ionic but has some covalent bonding present).

  6. List of radioactive nuclides by half-life - Wikipedia

    en.wikipedia.org/wiki/List_of_radioactive...

    This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds. [1]

  7. Ionic radius - Wikipedia

    en.wikipedia.org/wiki/Ionic_radius

    Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.

  8. Thermal ionization mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Thermal_ionization_mass...

    Thermal ionization mass spectrometer. Vacuum chamber on the left, electromagnet in the center, and ions detector on the right are visible.. Thermal ionization mass spectrometry (TIMS) is also known as surface ionization and is a highly sensitive isotope mass spectrometry characterization technique.

  9. Ion source - Wikipedia

    en.wikipedia.org/wiki/Ion_source

    An ion source is a device that creates atomic and molecular ions. [1] Ion sources are used to form ions for mass ... for example the Californium isotope 252 Cf.
