Electricity

Static Electricity-occurs when there is a build up of electric charge on the surface of a material.
-called static electricity because the charges do not move
-potential energy

Charge

-made up of the smallest atoms

*Estimation- about .0000000001m

-very small

-everything is made up of atoms

*Estimation- there is about 1500000000000000000000000000 atoms in a classroom

Inside Atoms

Particles

-electrons(-)

-protons(+)

-neutrons(0)

.Protons and Neutrons lump in nucleus

.Electrons orbit around nucleus

.mostly empty

.neutrons have no charge

.most things have the same number of electrons and protons

-dont have overall charge-most are neutral

Like magnets...

-opposites attract (+-)

-likes repel (++) (--)
