You are given a hammer, a battery, a bulb, wires and a switch. (a) How could you use them to distinguish between samples of metals and non-metals? (b) Assess the usefulness of these tests in distinguishing between metals and non-metals.

Answer
- Metals are malleable and can be easily drown into sheets by hitting with hammer. On the other hand, if we beat non-metals they break down and they cannot be drawn into sheets as they are non-malleable. Metals are good conductors of electricity, hence they make bulb when you connect metals with a battery, wire and bulb. Similarly, if non-metals are bad conductors of electricity, they fail to light up the bulb on connecting with wire and battery.
- These experiments can be helpful to demonstrate the malleability and electric conductivity of the metals and non-metals
