"Static" means
not moving.

Insulators
Draw a picture of an NEGATIVELY CHARGED atom
more electrons than protons
Located in the nucleus, has a +ve (positive) charge
Protons
Loss of static electricity as electric charges MOVE off an object.
Static DISCHARGE
A force that pushes objects apart.
Repel
Objects that hold electrons LOOSELY are called..
