Air Ions - in depth.
Air,
like all matter, consists of individual atoms that cluster
together
in different combinations to form molecules of the various gases of the
atmosphere,
(Nitrogen, oxygen etc.)
In turn, each atom is made up of even
smaller particles called Protons (which carry a
positive charge) and Electrons (carrying a negative charge).
Normally there are Neutrons too
- which, as their name suggests, have no charge.

This
diagram shows:
Blue:
Electrons - with a negative charge.
Red:
Protons - with a positive charge.
Green:
Neutrons - with no charge.
