Cards (5)

    • Helium - He
    • Neon - Ne
    • Argon - Ar
    • Krypton - Kr
    • Xenon - Xe
    • Radon - Rn
  • Properties
    • Non - flammable
    • Colourless
    • Monatomic - one atom in the molecule
    • Unreactive - due to full outer shell
  • Trends:
    • Boiling points increase down the group
    • Relative atomic mass increases
    • Atomic number increases
    • Electrons increase - which causes intermolecular forces to increase between atoms - so more energy needed to break them - so boiling points increase
  • Relative atomic mass = protons + neutrons
  • Atomic number = number of protons
