In 1941 Van Arkel recognised three extreme materials and associated bonding types. Using 36 main group elements, such as metals, metalloids and non-metals, he placed ionic, metallic and covalent bonds on the corners of an equilateral triangle, as well as suggested intermediate species.
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.
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
When ligands bind to the receptor, the ion channel portion of the receptor opens, allowing ions to pass across the cell membrane. Ligand-gated ion channel showing the binding of transmitter (Tr) and changing of membrane potential (Vm)

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.
Barium iodate, Ba(IO 3) 2, has a solubility product K sp = [Ba 2+][IO 3 −] 2 = 1.57 x 10 −9.Its solubility in pure water is 7.32 x 10 −4 M. However in a solution that is 0.0200 M in barium nitrate, Ba(NO 3) 2, the increase in the common ion barium leads to a decrease in iodate ion concentration.
