Characteristics of Electricity

Characteristics of ElectricityStatic ElectricityReview____________________ - smallest part of matter

Electrons- _________________ charge, orbit the nucleusProtons- positive charge, inside the nucleusNeutrons- neutral charge, inside the nucleus

Electrons Can MoveThe protons and neutrons in the nucleus are held together very tightly.

Some of the outer electrons are held very loosely.

They _____________move from one atom to another.

An atom that loses electrons has more positive charges (protons) than negative charges (electrons). It is positively charged.

An atom that _____________ electrons has more negative than positive particles. It has a _____________ charge.

Opposites AttractTwo things with _________________ , or different charges (a positive and a negative) will __________________, or pull towards each other. Things with the same charge (two positives or two negatives) will repel, or push away from each other.

Charged Objects and Neutral ObjectsA ________________ object will also _______________ something that is _________________. Example: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.many electrons move easily to the other side, as far from the balloon as possibleThe electrons in the atoms and molecules can only move very slightly to one side, away from the balloon leaving more positive charges closer to the negative balloon. Opposites attract. The balloon sticks.

Static ElectricityStatic electricity is the result of an _______________________ between negative and positive charges in an object.

These charges can ___________________ on the surface of an object until they find a way to be released or ______________________. Static Electricity ExampleThe rubbing of certain materials against one another can transfer negative charges, or electrons.

If you rub your shoe on the carpet, your body collects extra electrons.

The electrons cling to your body until they can be released.

As you reach and touch your friend, you get a shock.
