Properties of Nonmetals
- they do not luster or shine (except for the mirror which is composed of a silicone    element but is still considered as a non metal)
- they do not rust 
- generally they have less pressure resistance ( or weaker, in short)
- weak conductors of electricity or heat (except water)
