Electicity > Static

Static electricity is the imbalance of positive and negative charges. Simple science tells us that protons, neutrons, and electrons are very different from each other.
Protons have what we call a "positive" (+) charge. Electrons have a "negative (-) charge. Neurons have no charge, they are neutral.

Think about how you can make a balloon stick to the wall.
If you charge a balloon by rubbing it on your hair; it picks up extra electrons and has a negative charge. Holding it near a neutral object will make the charges in that object move.
If it is a conductor, many electrons move easily to the other side, as far from the balloon as possible.
If it is a insulator, the electrons in the atoms and molecules can move very slightly to one side, away from the ballon.
In either case, there are more positive charges closer to the negative balloon.
Opposites attract, and the balloon sticks.

In more scientific terms, triboelectrification is the process whereby charge transfer between dissimilar materials, at least one of which must have a high electrical resistivity; occurs due to rubbing or mere contact.

In the sixth century B.C., Thales of Miletus; who is usually credited with the discovery of static electricity; described experiments in which rubbed amber induced movements in nearby particles.

Static electricity has always been seen with basically the same concepts.; and many have used similar experiments to inquire this great force of nature.*
