  • The Periodic Table
    • Group 1: The Alkali Metals
      • Very Soft
      • Low melting Points
      • When water reacts with lithium, sodium and potassium, they react vigorously to form hydroxides.
      • Elements become more reactive further down as the atomic number increases.
    • The Transition Metals
      • All metals have high melting points.
      • Good conductors of heat and electricity.
        • They are insoluble.
      • They are malleable.
      • Metals consist of a regular lattice structure which are held together with metallic bonds.
        • Consists of positive ions and free electrons, this is because the bonds allow the outer electron to become de-localized.
    • Group 7; The Halogens
      • Very Reactive
      • A more reactive halogen can push out less reactive one from its compounds.
      • Halogens can react with hydrogen to form hydrogen hallides.
      • The Halogens react with metals to from metal halides.
      • More reactive halogens will displace less reactive ones.
      • The halogens all have 7 electrons in their outer shells.
      • Chlorine is a fairly reactive, poisonous, dense green gas.
      • Bromine is a dense, poisonous, orange liquid.
      • Iodine is a dark grey crystalline solid.
    • Group 8; The Noble Gases
      • They are all inert, colorless gases.
      • Everyday Uses
        • Argon is used to provide an inert atmosphere in filament lamps.
          • Can also be used to protect metals that are being welded, the inert atmosphere stops the hot metals reacting with oxygen.
        • Helium is used in airships and party balloons.
      • The boiling points and densities of the noble gases increase as you move down the group.
