Question

Differentiate between metals and non-metals.

Answer 1

Metals -

1) They are malleable
2) They are ductile.
3) They are mostly solids.
4) They are very hard and strong , except sodium and potassium
5) They are sonorous
6) They are lustrous
7) They conduct heat and electricity.
8) High melting and boiling points

Non Metals

1) They are not malleable.
2) They are brittle.
3) They are gases and liquids.
4) They are soft and slippery.
5) They are non sonorous.
6) They are non lustrous.
7) they don't conduct heat and electricity well.
8) Low melting and boiling points
