Electricity & Magnetism
[attachment=16562]
Atoms…
Have neutrons, protons, and electrons.
Protons are positively charged
Electrons are negatively charged
Electrons…
Are located on the outer edges of atoms…they can be moved.
A concentration of electrons in an atom creates a net negative charge.
Static Electricity
The build up of an electric charge on the surface of an object.
The charge builds up but does not flow.
Static electricity is potential energy. It does not move. It is stored.
If electrons are stripped away, the atom becomes positively charged
