The World of Metals and Non-metals — Question 13

Metals and non-metals have various properties that make them useful in our everyday life.
Metals:
Metals are malleable, for example, aluminium foil is used for wrapping food.
Metals are ductile, wires made of copper or aluminium are used in electrical fittings.
Metals are sonorous, they produce a ringing sound.
Metals are good conductors of heat, so they are used in making cooking vessels.
Metals are good conductors of electricity, making them ideal for electrical wires.
Non-metals:
Generally non-metals are poor conductor of heat and electricity; for example, sulphur and carbon are used in insulating materials to prevent the transfer of heat or electricity.
Non-metals are brittle: for example, sulphur and phosphoros are often used in matchsticks as they break easily or react quickly.
Non-metals are gaseous at room temperature: for example, oxygen is essential for breathing.
Non-metals are non-lustrous: carbon (as graphite) are used in pencils and dry cell batteries.
