Across
  1. 2. shine of an object
  2. 7. where non metals lay on the periodic table
  3. 10. not liquid or gas, it retains its form
  4. 13. when a substance melts at a low temperature
  5. 14. when an object has a lot of mass
  6. 15. when something easily allows electricity and thermal energy to flow through it
  7. 17. something that can easily be broken
  8. 18. when a metal can be become a thin wire
  9. 19. semi conductors, that typically appear metallic, but behave closer to non metals
Down
  1. 1. when something is blocks the flow of electricity and thermal energy
  2. 2. when an object has a small amount of mass
  3. 3. when a material can be hammered into thin sheets without breaking
  4. 4. blocks thermal energy and sound
  5. 5. characterized by being a bad conductor, being brittle, not being shiny
  6. 6. where metalloids lay on the periodic table
  7. 8. when something can both block and allow electricity and thermal energy to flow
  8. 9. where metals lay on the periodic table
  9. 11. characterized by being a good conductor, being ductile, being malleable, having luster
