What is an air ion?
Air Ions - very brief description.
The simplest way to visualise an air ion is as a tiny charge of 'static' electricity carried by the air. This can be either positive or negative.
However, the charged particles, or ions, are not merely suspended in the atmosphere, they actually are part of the 'fabric' of the air itself.
So as we breathe, they are taken into our lungs and absorbed into the bloodstream.
Air Ions - in more depth.
Air, like all matter, consists of individual atoms that bond together in different combinations to form molecules of the various gases that make up our 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.
