Metals, Nonmetals
and Metalloids
TEKS 6.6A compare metals, nonmetals and metalloids using physical properties such as luster, conductivity or malleability
TEKS 8.5C interpret the arrangement of the Periodic Table, including groups and periods, to explain how properties are used to classify elements
Video
Elements are classified into three groups on
the Table.
The groups are metals, metalloids and nonmetals.
Elements in the same group have similar physical and chemical properties.
Physical properties are:•Luster = reflect light.
(metallic or nonmetallic).
•Conductivity = conducts electricity.
Tested with a conductivity meter.
•Malleability = can be hammered into sheets without breaking.

•Ductility = can be pulled into a thin wire.

•Brittle = breaks easily.
•Magnetic
METALS are..
•on the left of the zigzag on the
Table.
METALS
BrainPop Metals
METALS are..1) Solid at room
temperature.*Except for mercury,
which is a liquid.
METALS are..
2) Good conductors of electricity and heat.
*But some are better conductors than others!
METALS are…
3) Lusterous which has a shiny/metallic appearance.
METALS are..4) Malleable and can be hammered into sheets
without breaking.
METALS are..5) Ductile and can
be drawn into wire.
METALS are..6) Sometimes
Magnetic
NONMETALS are…
•on the right of the zigzag line on the Table.
nonmetals
1) Solid, liquid or gas at room
temperature.
NONMETALS are…
NONMETALS are…
2) Bad (Poor) conductors of electricity and
heat.
NONMETALS are…3) Not lusterous and not shiny/nonmetallic in appearance.
NONMETALS are…
4) Brittle when they are solid.
NONMETALS are…
5) Never Magnetic
•On the zigzag line on the Table.
METALLOIDS..
metalloi
ds
*Exception is Aluminum. It is considered to be a metal
even though it lies along the
zigzag.
•Have no set characteristics.
•Share properties of both metals and nonmetals
METALLOIDS..
Examples•Good Conductor and Brittle
•Lusterous and Brittle•Magnetic and Brittle.
