  • Chemistry - C4
    • Alkali metals
      • Chemical properties
        • Alkali metals react with water to produce a metal hydroxide and hydrogen
        • Has a pH of 8 or more
      • Physical properties
        • Low density
        • Soft
        • Low melting points
      • Group 1 elements
    • Halogens
      • Group 7 elements
      • Physical properties
        • Come in pairs
        • Strong intermolecular forces
        • Melting and boiling points increase as you go down group 7
      • Chemical properties
        • React with metals to produce salts
        • Less reactive as you go down group 7
        • React with hydrogen to produce compounds
    • The noble gases
      • Group 0 elements
      • Physical properties
        • Low boiling points
        • Boiling point increases as it goes down the group
        • Low Density
      • Single atoms
      • Chemical properties
        • Very unreactive
        • Complete outer shells
    • Reactivity series of metals
      • 1. Gold (least reactive)
      • 2. Silver
      • 3. Copper
      • Hydrogen
      • 4. Iron
      • 5. Zinc
      • 6. Aluminium
      • 7. Magnesium
      • 8. Calcium
      • 9. Sodium
      • 10. Potassium (most reactive)
    • Metals and displacement reactions
      • Reactive and unreactive metals
        • A more reactive metal can displace a less reactive metal from its compound
      • Reactivity series
        • Displacement reactions
          • A piece of metal is dipped into a salt solution. Different combinations of metal and salt solution are tested
