  • EL Periodicity and the Periodic Table CI 11.1 SL EL4
    • Mendeleev and the Periodic Table
      • Mendeleev arranged the known elements in order of relative atomic mass
      • Elements with similar physical and chemical properties were in the same group.
      • Swapped elements if he thought they fitted better into another group  based on physical and chemical properties.
      • Left gaps for elements he thought were yet to be discovered.
      • Made predictions about properties of elements yet to be discovered.
    • Now arrange in order of atomic number rather than relative atomic mass.
    • Periodicity
      • Exhibited when
        • Regular pattern in a property as you go across a period.
        • Regular pattern is repeated in other periods.
