difference between metals and non-metals? write any 3 points.
Answers
Answer:
Whereas non-metals may be solid, liquid and gaseous at room temperature. Metals are good conductors of heat and electricity but non-metals are poor conductors of heat and electricity. Metals are ductile in nature i.e. it can be drawn into thin wires. ... Metals are malleable but non-metals are not malleable.
METALS
1) All metals are solid at room temperature except mercury, which is a liquid at room temperature.
2) All metals are lustrous.
3) Metals have high densities except lithium, soduim and potassium.
4) Metals are malleable.
5) Metals are ductile.
6) They are good conductors of heat and electricity.
7)They have high melting point.
NON-METALS
1) Non-metals exists as solid, liquid and gas.
silicon is a solid, bromine is a liquid and oxygen is a gas.
2) Non-metals are non-lustrous.
3) They have low density.
4) They are non-malleable.
5)They are non-ductile.
6) They are poor conductors of heat and electricity.
7) They have low melting and boiling point.
