Question

Elements are mainly classified into metals and non-metals. State six properties of metals which differ from non-metals.

Answer 1

Properties	Metals	Non-metals
1. State	Metals are generally solids at room temperature.	Non-metals are gases, liquids, soft solids at room temperature.
2. Lustrous	Metals have lustre i.e. shine.	Non-metals do not have lustre i.e. do not shine.
3. Malleability	Metals are malleable i.e. can be beaten into sheets.	Non-metals are non-malleable i.e. cannot be beaten into sheets.
4. Ductility	Metals are ductile i.e. can be drawn into wires.	Non-metals are non-ductile i.e. cannot be drawn into wires.
5. Conductivity	Metals are good conductors of heat and electricity.	Non-metal are poor conductors of heat and electricity.
6. Melting and Boiling point	Metals have high melting and boiling points.	Non-metals have low melting and boiling points.
7. Density	Metals have high density.	Non-metals have low density.
