  2. File:Binding energy curve - common isotopes.svg - Wikipedia

    en.wikipedia.org/wiki/File:Binding_energy_curve...

    Binding energy curve (average binding energy per nucleon in MeV against number of nucleons in nucleus) for a number of relatively common (abundant) isotopes (not chosen systematically; almost anything with an occurence of over .2 was chosen though a few exceptions are in there, such as U235).

  3. Ionization energy - Wikipedia

    en.wikipedia.org/wiki/Ionization_energy

    Ionization energy trends plotted against the atomic number, in units eV.The ionization energy gradually increases from the alkali metals to the noble gases.The maximum ionization energy also decreases from the first to the last row in a given column, due to the increasing distance of the valence electron shell from the nucleus.

  4. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    Electron transfer between lithium (Li) and fluorine (F). 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.

  5. Bent bond - Wikipedia

    en.wikipedia.org/wiki/Bent_bond

    One of the first bent bond theories for cyclopropane was the Coulson-Moffitt model (1947).. In organic chemistry, a bent bond, also known as a banana bond, is a type of covalent chemical bond with a geometry somewhat reminiscent of a banana.

    Description: DS1 Ion Engine Diagram. Caption from the source webpage: The ion propulsion system (IPS), provided by NSTAR (NASA SEP Technology Application Readiness), uses a hollow cathode to produce electrons to collisionally ionize xenon.

  7. Triple bond - Wikipedia

    en.wikipedia.org/wiki/Triple_bond

    Triple bonding can be explained in terms of orbital hybridization.In the case of acetylene, each carbon atom has two sp-orbitals and two p-orbitals.The two sp-orbitals are linear, with 180° bond angles, and occupy the x-axis in the cartesian coordinate system.

  8. Ion exchange - Wikipedia

    en.wikipedia.org/wiki/Ion_exchange

    Ion-exchange resin beads Ion-exchange column used for protein purification. Ion exchange is a reversible interchange of one species of ion present in an insoluble solid with another of like charge present in a solution surrounding the solid.
