Question

You are given a hammer, a battery, a bulb, wires and a switch.
How could you use them to distinguish between samples of metals and non-metals? [3 MARKS]

Answer 1

Each point: 1.5 Mark

1. We can use a hammer to beat the sample of metals and non-metals.
After beating, metals change into thin sheets (due to malleability) and at the time of strike, sound is also produced (due to sonorous property) but non-metals are broken into small pieces due to their brittle nature and they do not produce sound.

2. A battery, a bulb, wires and a switch can be used to set up an electrical circuit and test the samples of metals and non metals in this circuit.
We find that metals are good conductors of electricity and non-metals are bad conductors of electricity.
