Non Metal Definition Properties Examples
Position of non-metals
Non-metals are located on the right side of a periodic table. Especially all halogens and inert gases are non-metals. Other non-metals are scattered in group 13 to group 17.
Properties of Non-metals
1) Low metallic luster
Non-metals show no luster ie do not shine like metals.
2) Malleable or ductile
Non-metals are not ductile ie cannot be drawn into thin wire. also, they are not malleable ie cannot be beaten into the flat sheet.
3) Poor thermal conductor
Non-metals are the poor conductor of heat
4) Ionization energy
Due to the small atomic size, the ionization energy of non-metals is high.
Non-metals have high electronegativity due to small atomic size.
6) Poor electrical conductor
Non-metals are the poor electrical conductor. They do not contain free electrons. In group 13, Nitrogen and Phosphorus are bad conductors of electricity.
7) Metallic Luster
Non-metals show no luster ie do not shine
8) Gain electrons easily
Non-metals have the tendency to gain electrons easily
9) Lower melting points and boiling point
Since intermolecular bonds are weak, non-metals have low melting and boiling point.
