Ion Pair

Ion pairs are created when an Atom or molecule undergoes the process of Ionisation. They either loose or gain Electrons leading a net positive or negative charge. In simple terms, if water (H2O) undergoes ionisation it will form OH- and H+ ions (an ion pair).

Physics is really nothing more than a search for ultimate simplicity, but so far all we have is a kind of elegant messiness
