How could you use them to distinguish between samples of metals and non-metals?

Sure, here are the steps you could use to distinguish between samples of metals and non-metals:

1. Appearance: Metals usually have a shiny appearance, they are often lustrous, while non-metals may not be.

2. Conductivity: Metals are good conductors of electricity and heat, while non-metals are not. You could test this by trying to pass an electric current or heat through the sample.

3. Malleability and Ductility: Metals can be hammered into thin sheets (malleability) or drawn into wires (ductility). Non-metals usually break when hammered or pulled.

4. Sound: Metals produce a ringing sound when hit, known as sonorous. Non-metals do not produce a similar sound.

5. Density: Metals usually have a high density and are heavy for their size, while non-metals have a lower density.

6. Melting and Boiling Points: Metals usually have high melting and boiling points. Non-metals have lower melting and boiling points.

Remember to always handle samples with care and use appropriate safety equipment, especially when dealing with electricity or heat.
