Explanation:

physical properties of metals:

1.metals tend to have 1-3 electrons in valence shell

2.can conduct electricity

3.loose electrons

4.can conduct hear

5.high melting point

6.high boiling point

7. lustrous

8. malleable

9. ductile

10. sonorous

11. have metallic bond

12. example: iron , gold, silver, platinum

physical properties of non metal:

1.tend to have 4-8 electrons in the valence shell

2.can't conduct electricity

3.gain electrons

4. can't conduct heat

5. low melting point

6.low boiling point

7.non lustrous

8.non malleable

9. non ductile

10. non sonorous

11.have covalent bond

12. example: chlorine, carbon

chemical properties of metal:

metal + o2= metallic oxides

metal+ h20= metallic hydroxide

metal + acid = salt+ h2

metal + base=salt+ h2

chemical properties of non metal:

nonmetal + o2= non metallic oxides

non metal + h2o= no rxn

non metal + acid=no rxn

non metal + base= salt

exceptional cases of metals and non metals:

non metals are lustrous except

iodine and graphite

metals are hard except

sodium and potassium

non metals are not hard except

diamond

metals are malleable except

zinc, arsenic, antimony

metals are ductile except

zinc, arsenic , antimony

non metals are non ductile except

carbon fiber

metals are good conductors of heat and electricity except

bismuth

tungsten

non metals are bad conductors of heat and electricity except

graphite

metals are solid except

mercury

gallium

metals have high density except

sodium , potassium

non metals have low density except

diamond
