Across
- 3. of charge no charges (electrons) are created or destroyed just moved around
- 5. charges attract "negative charges"
- 6. force The force between charged objects
- 8. an atom loses electrons it becomes positively charged
- 10. found outside of the atom and has a negative charge
- 12. an atom have a charge? atoms usually have the same number of electrons and protons- ( no charge) but when they gain extra electrons or lose electrons they can become charged.
- 13. drawn together
- 16. part of the nucleus of the atom- has NO charge
- 18. an atom gains electrons it becomes negatively charged
- 19. part of the nucleus of the atom- has a positive charge
- 20. pushed apart
Down
- 1. field a region around a charged particle that can exert a force on another charged particle
- 2. strength of an electric force is determined by… 1. the size of the charge- bigger charge= bigger force 2.the distance between the charges- the closer the charges the stronger the force
- 4. a material in which charges cannot move easily. The electrons are tightly bound to the atom and do not flow. Examples include rubber, plastic, glass, wood, air and ceramic. They are used to cover wires and prevent shock
- 7. a material in which charges move easily, examples most metals and tap water.
- 9. of charge "the parts of the atom that create charges cannot disappear, they can only be moved from one place to another"
- 11. of electric charges Like charges repel and opposite charges attract.
- 14. a property of matter that is responsible for electrical properties. There are 2 types, positive and negative
- 15. flow of charged particles that carry electrical energy
- 17. unit of electrical current
- 19. energy The amount of energy stored based on the position and size of the charge. Bigger charges and closer charges have more potential energy
