  • Trends of Groups within the Periodic Table
    • Group 1
      • increasing reactivity
        • the outer electron is more easily lost as the attraction between the nucleus and electron decreases, because the electron is further away from the nucleus the further down the group you go
      • melting + boiling points decrease
      • relative atomic mass increases
    • Group 7
      • decreasing reactivity
      • melting + boiling points increase
      • relative stomic mass increases
    • Group 0
      • melting + boiling points increase
        • the increase is due to an increase in the number of electrons in each atom leading to greater intermolecular forces between them which need to be overcome.
