B Electrons and ions -- how long can they exist apart?

    Can ions exist by itself, if it does, does it last for short period of time before it reacts with something else.

    In the case of a gas, the ion can remain existing until it has a collision and a recombination. For instance, in the upper atmosphere, the F region of the ionosphere remains ionised all night after the source of ionisation, which is the Sun's radiation, has disappeared. On the other hand, the D region of the ionosphere, where the pressure is higher and collision/recombination more likely, disappears as soon as the Sun sets.

    What happen when ionisation happen to solid state
