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 distingished by the following properties:
$\bullet$ Lustre: The ability of a material to shine
$\bullet$ Ductility: The property by which a material can be drawn, bent, or twisted into thin wires
$\bullet$ Sonority: The ability of a material to produce a ringing sound when struck
$\bullet$ Malleability: The property of a material by which it can be pressed or rolled into thin sheets
$\bullet$ Conductivity: The measure of a material's ability to transmit heat or electricity
Genrally, metals show all the above mentioned properties. Whereas, non-metals do not exhibit any of them.
