Metals are chemicals elements that are
distinguished by certain properties:
•
•
•
•
•
Luster
Strength
Hardness
Ability to conduct electricity
Ability to conduct heat
Advantages associated with metals:
-
Good conductors of electricity and heat
-
They do not break easily (high density, high
melting point and boiling point)
-
They are malleable: can be hammered into
different shapes
-
They are ductile: can also be drawn into wires
without breaking

Properties of metals
Mohs scale of mineral hardness
Varying properties of metals
•
Hardness: hard to soft , scratched or not
•
Density : the number of grams per cubic meter. Density varies from
metal to metal
•
Tensile strength: to withstand a stretching force(application cables
and bridges)
•
Melting point: solid to liquid temperature
•
Mercury is the only liquid metal at room temperature
•
Chemical reactivity :reactions with other substances some are
unreactive, others react with water and some are explosive
Metals
Exploration: Per group,
- read the the document:
https://fractory.com/types-of-metal/
- Color the different types of metals in the
periodic table given to you. Stick it in your
notebook
ATL Skills:
- Information literacy
- Collaboration
- Communication
Metals are elements. We organize them in
the periodic table under several groups:
-
Alkali Metals,
-
Alkaline Earth Metals,
-
Transition metals,
-
and Metalloids.
Alkali Metals

Watch the slide show and ask students for their
reflections using padlet
Very interesting !!!!!!!
Transition metals
