This document provides information about the properties of metals, nonmetals, and metalloids. It defines metals as good conductors of heat and electricity that are shiny, ductile, and malleable. Nonmetals are described as poor conductors that are dull, brittle, and often gases. Metalloids have properties between metals and nonmetals, conducting some heat and electricity but not as well as metals. The document instructs students to color and label their periodic tables accordingly.
4. • Put the colored periodic table to the side, we
will glue it in later
• Find this page, we will begin taking notes:
5. Metals
• Most elements are metals.
• The 88 elements to the left of the stair step line
are metals or metal-like elements except
Hydrogen.
Examples of metals:
6. Physical Properties
• A physical property is
a characteristic you
can observe or
measure
• In our lesson
yesterday, we focused
on physical
properties.
• For example, a
physical property of
some metals are that
they are shiny.
7. Physical Properties of Metals
• Good conductors of
heat and electricity.
• Luster: shiny
• Ductile (can be
stretched into thin
wires)
• Malleable (can be
pounded into thin
sheets)
8. Properties of Metal, Cont.
• Usually solids at room temperature
• High melting points and boiling points (except
Hg - Mercury)
• High densities and
reflect light
9. Chemical Properties of Metals
• A chemical property of metals is that it
Corrodes easily
– Gradual wearing away
– Ex: Silver tarnishing or iron rusting
10. What are Chemical Properties?
• A chemical property may only be observed by
chemical reaction.
• This property measures the potential for
undergoing a chemical change.
• A chemical reaction is the process by which one
or more substances change to produce one or
more different substances.
11. Say what?
• Ok, let’s look at it another way:
• Why is Mater the color of orange dirt?
Rust (that orange
coloring) is caused by
iron coming into contact
with oxygen molecules.
That ability to react with
oxygen is a chemical
property of iron!
12. Metalloids
• The periodic table contains a stair-step line,
these elements along that line are called
metalloids.
• The “-oid” ending means – like or similar to
• Elements in this group have properties of both
metals and non-metals.
13. Physical Properties of Metalloids
• Solids that can be shiny or
dull.
• They can conduct heat and
have electrical charges,but
not as well as metals.
• They are ductile and
malleable.
Silicon
14. Non-Metals
• Nonmetals are found on the right side of the
periodic table.
• Their characteristics are opposite those of
metals.
15. Physical Properties of Non-Metals
• poor conductors of
heat and electricity.
• Non-metals are not
ductile or malleable.
• Solid non-metals are
brittle and break easily.
• Dull, no shiny luster,
don’t reflect light.
• Many non-metals are
gases.
Sulfur
16. Important Words to Know!
• So now that you’ve got a good understanding of
metals, nonmetals and metalloids…
• Let’s make sure you know the properties that
describe them!
19. Conductor
• Allows heat or electrical charge can pass through
material
• Does metal have good conductivity? Give me an
example!
20. Insulator
• Does not allow electricity to pass through easily
– Known as a poor conductor, what in this picture
would you consider to be the insulator?
21. Luster
• The way matter reflects light from its surface
• Matter that reflects a large amount of light is
called SHINY (write: high light=shiny)
• Matter that reflects little light from its surface is
called DULL. (write: low light=dull)
24. Next …..
• Find this page
• Color these properties to
match the periodic table
of elements
Metals – blue
Non-metals – green
Metalloids – purple
• Now glue these in UNDER
your periodic table
25. This is what
your page in
your science
notebook will
look like when
we are done.
METALS
•Good conductors of heat and electricity
•Luster is shiny (reflect light)
•Ductile
•Malleable
•Corrosive in water
•Solid at room temperature
•High density
•High melting point and boiling points
NON-METALS
•Poor conductors of heat and electricity
•Luster is dull (don’t reflect light)
•Non Ductile
•Not Malleable
•Brittle
•Exist in 3 states of matter (but many are gases)
METALLOIDS
•Have properties of both metals and non-metals
•Luster is shiny or dull
•Ductile
•Malleable
•Do conduct heat and electricity, but not as well as metals
