What is Static Electricity?
Everything we see is made up of tiny little parts called atoms. The atoms are made of even smaller parts. These parts are called protons, electrons and neutrons. They are very different from each other in many ways. One way they are different is their “charge.” Protons have a positive (+) charge. Electrons have a negative (-) charge. Neutrons have no charge.
Usually atoms have the same number of electrons and protons. Then the atom has no charge. It is “neutral.” But if you rub things together, electrons can move from one atom to another. Some atoms get extra electrons. They have a negative charge. Other atoms lose electrons. They have a positive charge. When charges are separated like this, it is called static electricity.
If two things have different charges, they attract, or pull towards each other. If two things have the same charge, they repel or push away from each other.
