Answer 2

Answer- The above question is from the chapter 'Metals and Non-Metals'.

Given question: Use five physical properties to compare and contrast metals and non-metals.

Answer: Difference between metals and non-metals using their physical properties are:

1. Metals are lustrous while non-metals are non-lustrous.

2. Metals are ductile while non-metals are not ductile.

3. Metals are malleable while non-metals are not malleable.

4. Metals are good conductors of heat and electricity while non-metals are poor conductors of heat and electricity.

5. Metals are sonorous while non-metals are non-sonorous.

More points of difference:

6. Metals are not brittle while non-metals are brittle.

7. Metals are usually solids at room temperature (25K) while non-metals are either solids or liquids or gases at room temperature (25K).

8. Metals usually possess high melting points while non-metals usually possess low melting points.

9. Metals usually possess high boiling points while non-metals usually possess low boiling points.

10. Metals usually have high densities while non-metals have low densities.
