2. Directions:
• Click “Slideshow” and “From Beginning” to
view this presentation properly.
• Make a 3 column chart and label the columns
metals, Nonmetals, or Metalloids.
• As you go through the presentation list the
physical AND chemical properties of each.

3. Metals

4. Properties of
Metals
Metals appear to the left of the dark zig-zag line on
the periodic table. Most metals are solid at room
temperature.

5. Properties of
Metals
Metals have shiny
metallic
Luster

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

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

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

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

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

11. Nonmetals

12. Properties of Nonmetals
Nonmetals occur to the right of the dark zig-zag on the
periodic table. Although Hydrogen is in family 1, it is also
a nonmetal. Many nonmetals are gases at room
temperature.

13. Properties of Nonmetals
Nonmetals have
nonmetallic
luster; they
tend to be 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. Metalloids

18. Properties of Metalloids
Metalloids can be found clustered around the dark
zig-zag line that separates metals and
nonmetals.

19. Properties of Metalloids
Metalloids (metal-like)
have properties of
both metals and
nonmetals.

20. Properties of Metalloids
Metalloids are solids
that can be
shiny or dull.

21. Properties of Metalloids
They are “okay”
conductors of
electricity and
heat - better than
nonmetals but not
as well as
metals.

22. Properties of Metalloids
Metalloids can be
malleable and
ductile but not
always.

23. If a substance can be pulled
into thin wires and is a dull tan
color, what is it?
metalloid

24. If you have a copper colored
material that you can hammer
into the shape of a coin what
do you have?
metal

25. If you find something that
does not reflect light very well,
keeps you warm, and will just
tear if you stretch it, what do
you have?
nonmetal
