Metals are good thermal and electrical conductors, they are strong, shiny, malleable and ductile.
Non-metals are normally poor thermal and electrical conductors, they are not strong, and are dull and brittle.
Graphite is a non-metal that is a good electrical and thermal conductor.
Metals are found on the left side and in the middle of the periodic table, non-metals on the right side.

There are exceptions for both metals and non-metals, which have different properties.

Use examples such as mercury and graphite in your teaching.

Thermal conductor - A thermal conductor is a substance that transfers heat from one place to another place.
Electrical conductor - An electrical conductor is a substance that allows a flow of charge (electrical current).
Malleable - A malleable substance has the ability to be formed into a shape.
Brittle - A brittle substance has the ability to break up easily.
Ductile - A ductile substance has the ability to be pulled into a wire.
