Identifying Metals and Nonmetals by Physical Properties

1. Identifying Metals and Nonmetals by Physical Properties Objective: Compare metals, nonmetals and metalloid using physical properties.

2. Sort Items by Content of Material Made of Metal Not Made of Metal Non Metals • Metals

3. Sort Items by Physical property: Luster Shiny Shiny Dull Non Metallic • Metallic Metal like shine

4. Sort Items by Physical property: Malleability Malleable Shiny Brittle Brittle breaks into pieces • The ability to be flattened into a sheet. • Mallet flattens malleable objects.

5. Problem: What physical properties are common in metals?

6. Observations: Review physical properties of matter. Physical Properties of Matter MagneticLusterBrittleElectrical ConductivityMalleability _______________________is a physical property that describes how electricity can be conducted or carried through an object. Matter can be classified as a GOOD conductor of electricity or a POOR conductor of electricity. 2. _______________________is a physical property that describes if matter is attracted to a magnet. 3. _______________________is a physical property that describes how matter interacts with light. Matter that reflects light is SHINY, or has aMETALLIC LUSTER. Matter that does not reflect light is DULL, orhas a NONMETALLIC LUSTER. 4. _______________________is the physical property that describes matter that can be hammered into thin sheets without breaking. The opposite of malleable is __________________, which breaks easily when struck or hammered.

7. Hypothesis:: I hypothesize that metals will have the physical properties checked below. Electrical Conductivity Magnetic _____good conductor of electricity _____will attract to a magnet _____poor conductor of electricity _____will not attract to a magnet Luster _____Malleable: will flatten into sheets without breaking _____Metallic or Shiny _____Brittle: breaks easily if struck or hammered _____Nonmetallic or Dull

8. Collect Data:

9. Study Data and Conclusion: • Review the table. Check the physical properties that all metals had in common. • Electrical Conductivity Magnetic • _____good conductor of electricity _____will attract to a magnet • _____poor conductor of electricity _____will not attract to a magnet • Malleability • Luster _____Malleable: will • flatten into sheets without breaking • _____Metallic or Shiny _____Brittle: breaks easily • if struck or hammered • _____Nonmetallic or Dull

10. Study Data and Conclusion: • 1)My hypotheses was or was not supported. I learned the physical properties of metals are ___________________________________________________________ ____________________________________________________________________ • 2) The only metal that will attract to a magnet contains _____________________.

11. Question/Sentence Starters: The physical property _______________ is opposite of ________________ because …. Stand up if you believe a nonmetal could have the physical property _______________ Explain your answer. Name the physical properties all metals have in common. One physical property all metals have in common is __________________. metallic in luster magnetic

12. Application: Use the Element Cards to complete the table. • What is the probability that a nonmetal would have all the physical properties listed in our conclusion? • Electrical Conductivity • _____good conductor of electricity • Malleability • Luster _____Malleable: will • flatten into sheets without breaking • _____Metallic or Shiny • Find the Elements that have the same physical properties of metals that you discovered in your comparative investigation. Complete the chart with metals and their symbol.
