Across
- 3. a substance that allows the flow of electrical charge or transfers thermal energy through matter
- 6. a substance that shows the property of electrical conductivity between a conductor and insulator
- 10. tendency to break, snap, or crack without first bending as a result of force
- 11. they have properties of both metals and nonmetals; sometimes called semiconductors
- 12. a table in which all the known elements are arranged by properties and represented by symbols
- 13. most elements are this; they are typically solid, shiny, malleable, and good conductors of heat
Down
- 1. the ability or power to easily transfer heat, electricity, or sound
- 2. a characteristic that can be observed or measured without changing the substance
- 4. they are typically not shiny, not malleable, and poor conductors of heat and electricity.
- 5. able to be shaped or formed into thin sheets by hammering or pressure
- 7. able to be shaped or formed into wires
- 8. a substance that resists electrical current, or a material that resists the flow of heat
