The properties typical of metals include:

1. Shiny or glossy: Metals have a shiny appearance when they are polished.

2. Conduct electricity: Metals are good conductors of electricity.

3. Can be flattened into sheets: This property is known as malleability. Metals can be hammered or rolled into thin sheets.

4. Can be stretched into threads or wires: This property is known as ductility. Metals can be drawn into thin wires.

However, the properties "Dull or matt", "Brittle or easily broken", and "I'm not sure" are not typical of metals. Metals are usually not dull or brittle. They are hard, strong, and resistant to wear and corrosion.
