Term 2 Topic 1 Properties of Non-metal

• Non-metals are dull, can break easily (brittle).
• Non-metals are not necessarily shiny and are usually dull.
• Non-metals are brittle, meaning, when we band them with enough force they may bend or break.
• Non-metals are not conductors of electricity and they do not heat well. We refer to them as insulators.

No, they don’t shine, they don’t feel cool, they are not hard, they don’t bend, etc.
