Natural Science
Across
- 5. this provides the electrical energy
- 9. this occurs when electrons are passed quickly from one atom to another within certain materials
- 11. this opens and closes the circuit and can stop the flow of electricity
- 14. this occurs when there is an imbalance of positive and negative charges between two electrical insulators
- 15. all matter is made up of this tiny structure that is not visible to the naked eye
Down
- 1. conductors of electricity
- 2. negatively charged part of an atom that moves around outside the nucleus
- 3. a component inside the nucleus but have no electric charge
- 4. example of a positively charged matter
- 6. example of a negatively charged matter
- 7. positively charged component inside the nucleus
- 8. central part of an atom
- 10. this transforms electricity into other forms of energy
- 12. this material allows electrons to flow through a path
- 13. this is what happens when negative charges meet another negatively charged object or positively charge to another positively charged object
