Prepare a list of the uses of metals and nonmetals in our everyday life. Name of metal Use Name of non-metal Use

Metals are usually hard, malleable, ductile and are lustrous in their appearance. Similarly, non-metals are usually brittle and are non-lustrous in nature. Both of them have got do many uses in different fields. They can be given as, Name of metal Use Name of nonmetal Use Gold Used for decorative arts, ornaments and coins. Oxygen Essential to human life and an important element in combustion. Iron Used to build structures, ships and vehicles. Chlorine A powerful disinfectant. Copper It is used for making electric wires and other utensils. Nitrogen It is used in fertilisers. Aluminium Used for making packaging foils, vessels, etc. Carbon (graphite) Graphite, a form of carbon is used for making pencil leads.

Complete the table: Property of metal Use in everyday life i. Ductility ii. Malleability iii. Conduction of heat iv. Conduction of electricity v. Sonority

Metals can be hammered into thin sheets and wires. These properties are known as malleability and ductility. Generally metals are good conductors of heat and electricity, and they produce sound when they are hit together. That is, they are sonorous in nature. On the basis of these physical properties. They are used in many fields. They can be tabulated as, Property of metal Use in everyday life i. Ductility Copper, because of ductility, it is used in making wires. ii. Malleability Gold is a malleable metal which is used for making ornaments. iii. Conduction of heat Iron pan is used to make roti. The iron is a good conductor of heat. iv. Conduction of electricity Copper is a good conductor of electricity and hence it is used for making electric wires. v. Sonority Because of sonority, metals are used in making guitar strings and other musical instruments.
