Metallic elements

I can describe the properties of metal elements and compare them to non-metal elements.

Lesson details

Key learning points

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

Common misconception

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

Use examples such as mercury and graphite in your teaching.

Keywords

  • 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.

Use graphite to demonstrate electrical conductivity.
