Question

State any five physical properties of non-metals.

Answer 1

1. Non-metals are brittle (break easily). They are neither malleable nor ductile.
2. Non-metals are bad conductors of heat and electricity (except graphite, which is a good conductor of electricity).
3. Non-metals are non-lustrous (dull) and cannot be polished (except iodine, which is a lustrous non-metal).
4. Non-metals may be solid, liquid or gases at room temperature.
5. Non-metals are not strong or tough.
