Metals

• Reactions of metals and water

  • Lithium + water
  • Sodium + water
  • Potassium + water
  • Rubidium + water
  • Caesium + water
  • Francium + water
• Metallic bonding structure

  Consists of positive metal ions and a sea of delocalised (free moving) electrons
• Many metals react with water

  • A metal hydroxide is formed
  • Hydrogen is produced
• Metals react with oxygen


  A metal oxide is formed
• Metals


  Metallic bonding is the electrostatic force of attraction between positively charged ions and delocalised electrons
• Alkali metals react with water

  • Produce hydrogen and alkali hydroxide
  • Water turns purple indicating an alkali has been added
• Metal + Oxygen

  • Metal oxide
• Alkali metals react with acids


  • A metal salt is formed
  • Hydrogen is produced
• Reactions of metals and acids

  • Lithium + acid
  • Sodium + acid
  • Potassium + acid
  • Rubidium + acid
  • Caesium + acid
  • Francium + acid
• Metallic bonding


  • Allows metals to conduct electricity even when solid
  • Variation in melting and boiling points
