• Where are non-metals located in the periodic table


  Far right and top
• Why do metals form positive ions


  Don't have electrons to remove or outer electrons are far from nucleus so feel a weaker attraction. This means not much energy is needed to remove electrons
• Properties of metals


  1. strong but malleable
  2. conduct heat and electricity
  3. high boiling and melting points
• Properties of non-metals


  1. dull looking
  2. brittle
  3. aren't always solids at room temperature
  4. don't conduct electricity
  5. lower density
• Where are transition metals in the periodic table

• Properties of transition metals


  1. can have more than one ion
  2. often coloured so compounds with them are colourful
  3. make good catalysts
