Question

State any five physical properties of metals and five physical properties of non-metals.

Answer 1

Five physical properties of metals are:

1. Metals are malleable and ductile.
2. Metals are good conductors of heat and electricity.
3. Metals are lustrous (shiny) and can be polished.
4. Metals are solids at room temperature (except mercury, which is liquid).
5. Metals are tough and strong.

Five physical properties of non-metals are:

1. Non-metals are brittle. They are neither malleable nor ductile.
2. Non-metals are bad conductors of heat and electricity (except graphite).
3. Non-metals are non lustrous (dull) and cannot be polished (except iodine).
4. Non-metals may be solids, liquids or gases at room temperature.
5. Non-metals are neither tough nor strong.
