- 3. Electricity: a buildup of electrical charge in an object that occurs when there is an imbalance of negative and positive charges
- 4. a material that does not allow the flow of electricity or heat
- 6. charge: If an atom has a greater number of electrons than protons, it has a negative charge.
- 10. a material that allows electricity to pass through it easily.
- 12. circuit: an electrical circuit that is complete, with no breaks or open switches, and allows electricity to flow through the circuit:
- 14. a tiny particle inside the center of an atom that has a positive charge
Down
- 1. to pull two things towards each other by a physical force
- 2. a tiny, negatively charged particle that circles around the nucleus of an atom
- 5. a tiny particle found in the center of an atom (called the nucleus) that has no electrical charge
- 7. Energy: is a type of energy created by the movement of tiny charged particles called electrons, flowing through a conductor like a wire
- 8. the smallest particle of an element that still has the properties of that element
- 9. the central area of the atom
- 11. To force something to move away or apart.
- 13. charge: occurs when an atom has more protons than electrons.
