I have a sweet moggy, but unfortunately she isn't much interested in cuddles. She will, however, let me have the occasional pat!
Okay negative ions. Quick chemistry tute! I'll do my best to explain, and I'll assume no prior knowledge (so please excuse me for talking at you as if you are 5yrs old).
Everything in this world (including you!) is made up of tiny particles called atoms. Atoms have a central core, in which resides neutrons (these have a no charge) and protons (these are positive). Surrounding the core are electrons (negative charge).
An atom is most stable when it has a certain number of protons and electrons. Thus, sometimes an atom will lose or gain protons or electrons. This produces an ion. More protons than electrons = positive charge, and therefore a positive ion (sometimes called cation).
Thus, a negative ion (or anion) is an atom that has more electrons than protons, (promoting stability for that atom)= a negative charge.
Confused yet? :)
Negative ions are said to be a natural anti-depressant in the air, and that is why it is suggested sometimes for people with depression to get a negative ion air generator.
Search for negative ions on the net, and a whole stream of sites about negative ion air generators appears. Also, apparently comps emit positive ions; so don't spend too much time at PB!!!
