- There are two kinds of charge: positive and negative.
- An object with equal amounts of the two kinds of charge is electrically neutral, whereas one with an imbalance is electrically charged.
- The two glass rods were each rubbed with a silk cloth (positively charged) and one was suspended by thread. When they are close to each other, they repel each other.
- The plastic rod was rubbed with fur (negatively charged). When brought close to the glass rod, the rods attract each other.
- Positive

- Atoms consist of positively charged protons, negatively charged electrons, and electrically neutral neutrons. The protons and neutrons are packed tightly together in a central nucleus.
