Atoms and Static and Electricity

An object becomes charged when the atoms in the object gain or lose

• electrons
• protons
• neutrons
• all of the above

Objects that have opposite charges

• are attracted to each other, and the force between the objects pulls them together.
• are attracted to each other, and the force between the objects pushes them apart.
• are repelled by each other, and the force between the objects pulls them together.
• are repelled by each other, and the force between the objects pushes them apart.

If a substance has a higher number of electrons than protons on its surface, what type of charge does it have?

• A positive charge.
• A negative charge.
• A neutral charge
• No charge at all

What charge does a proton have?
