1.	You are given a hammer ,a battery , a bulb wires and a switch
Answer» Answer: If the SUBSTANCE can be hammered to convert into SHEETS then it is METAL if it is broken into pieces then it is non-metal. Set up the circuit arrangement using BULB, battery, wire and switch. Place the object between the ends of circuit. If the bulb starts GLOWING then the substance is a metal otherwise it is non-metal because metals are good conductor of electricity. Generally above methods can be used to identify metals and non-metals. But there are some exceptions also for example sodium is metal which is not malleable in fact it is brittle. Graphite, allotrope of non-metal carbon, is a good conductor of electricity.
