Question

Write down any five properties along with their definitions by which metals and non-metals are distinguished.

Answer 1

Metals and non-metals can be distinguished by the following properties:
$\bullet$ Lustre: The ability of a material to shine. Metals are generally lustrous while non-metals are generally non-lustrous.

$\bullet$ Ductility: The property by which a material can be drawn, bent, or twisted into thin wires. Metals are generally ductile while non-metals are generally non-ductile.

$\bullet$ Sonority: The ability of a material to produce a ringing sound when struck. Metals are generally sonorous while non-metals are generally non-sonorous.

$\bullet$ Malleability: The property of a material by which it can be pressed or rolled into thin sheets. Metals are generally malleable while non-metals are generally non-malleable.


$\bullet$ Conductivity: The ability of a material to allow the passage of heat and electricity through them. Metals are generally good conductors of heat and electricity while non-metals are generally poor conductors of heat and electricity.
