Revision Chapter 2 (metals, non-metals, and alloys) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. On the periodic table, metals are arranged on the left or right side? left Give 2 examples of metallic element sodium potassium Define elements cannot be split into anything simpler Define alloys? mixture of two metals(or more) Use a diagram to show the particles in alloys are arranged? Define 1. 2. 3. 4. 5. Malleable-can be beaten into sheets Ductile-can be drawn into wires strong – can support heavy loads Flexible- can be bent easily Tough-can withstand impacts How does metal conduct electricity? They havefree moving electrons How does metal conduct heat? Atoms gain KE and pass this energy to neighboring atoms Explain why are non-metals not malleable? layers of atoms cannot slide over each other Explain why are non-metals weak(not strong)and brittle? Non-metlas have weak force of attraction between particles
