What to Focus On

  • Metals are malleable, ductile, lustrous, sonorous, dense, and good conductors.
  • Non-metals are generally brittle, dull, low-density, and poor conductors.
  • Mercury is the only liquid metal at room temperature.

  • Metals lose electrons; non-metals gain electrons.
  • Metal oxides are generally basic.
  • Al2O3, ZnO, SnO, and Fe2O3 are amphoteric oxides.

  • Corrosion is the destruction of a metal surface by air and moisture.
  • Rusting is corrosion of iron.
  • Rust is hydrated ferric oxide.

Common Mistakes to Avoid

All metals are hard, so sodium must also be hard.

Mercury is a non-metal because it is liquid at room temperature.

All non-metals are dull and never show metallic lustre.

Memory Tips

Basic difference between metals and non-metals

Metals are malleable and ductile

Non-metals are mostly neither malleable nor ductile

Mercury and bromine are the liquid exceptions at room temperature
