2. Review of an Atom  What makes up an atom?  What happens if I take away an electron?

3. Charges  Which ones is which diagram?  Neutral Charge  Negatively Charged Object  Positively Charged Object

4. Static Electricity  The imbalance of electrical charge on the surface of an object  Example making your hair positively charged, and a balloon negatively charged as you rub the balloon on your head

5. Law of Electric Charges States that  Objects that have like charges repel each other  Objects that have opposite charges attract each other  The strength of the Electrical Force is related to the distance between the two objects and the amount of charge on each object

6. Induced Charge Separation  When you bring a charged object towards a neutral object, it causes the electrons to shift position  The electrons move according to the Law of Electric Charges  What does that mean?

7. Charging by Friction  When two objects come into contact and are rubbed against each other, one is more likely to attract the electrons than the other  If it had extra electrons it has what kind of charge?

8. Electrostatic Series  As you move down the list there is a higher tendency to gain electrons.

9. Charging by Conduction  When two objects with different amounts of electrical charge come into contact and the electrons move from one object to another  Electrons always move from the more negative object to the one that is less negative to evenly distribute the charge

10. Grounding  Removing the electrical charge by transferring electrons between a charged object and a large neutral object (eg. Earth)  Electrons can transfer from the object to the neutral object, in which case you can get a shock  Or electrons can travel from the neutral object to your charged object to balance out the positive charge.
