Metals have properties of luster, conductivity, malleability, and ductility. They are solid except for mercury and have high density. Metals are good conductors of heat and electricity. Nonmetals have properties of being dull, brittle, poor conductors, and low density. Most nonmetals exist as gases at room temperature. Metals tend to lose electrons in chemical bonds while nonmetals tend to gain electrons in chemical bonds.

1. Metals

2.  Have Luster -shiny
 Are Conductors -heat and electricity move
through them easily
 Malleable – Can be hammered into a different
shape
 Ductile – Can be drawn into a wire
 High Density – Heavy for their size
 Metals are solid, except for mercury

4.  Dull – not shiny
 Nonconductors – heat and electricity do not
move through easily
 Brittle – break easily
 Most nonmetals are gases at room temperature

6. Properties of Metals
Metals have
luster. This
means they are
shiny

7. Properties of Metals
Ductile
metals can be
drawn into wire.

8. Properties of Metals
Malleable
metals can
be hammered
into sheets

9. Properties of Metals
Metals have a high melting point. They
are also very dense.

10. Properties of Metals
Conductors
Metals are
good
conductors of
electricity and
heat

11. Properties of Metals
A chemical property
of metal is its
reaction with
water and oxygen.
This results in
corrosion and
rust.

12. Nonmetals

13. Properties of Nonmetals
Nonmetals do
not have
luster; they are
dull.

14. Properties of Nonmetals
Brittle
Nonmetals are
brittle so they
break easily.
This means
nonmetals ARE
NOT ductile or
malleable.

15. Properties of Nonmetals
Nonmetals
have low
density.

16. Properties of Nonmetals
They also have a
low melting point.
This is why they
are poor
conductors of
heat and
electricity.

17. Chemical Properties of Metals
Most metals
have 3 or less
valence
electrons
and
therefore are
likely to lose
these
electrons in
chemical
bonds.

18. Nonmetals have 5 or more valence
electrons and therefore usually gain
electrons in chemical bonds.
