Electric Charges: Positive and Negative
There are two kinds of electric charges: positive charge (+) and negative charge (-).

- The closer two objects with different signs of charge are, the more they attract each other.
- A body with no electrical charge has the same number of protons as electrons.
- A body with a negative electric charge has gained electrons.
- A body with a positive electric charge has lost electrons.
