8. The Periodic Table

Arrangement of elements, Group I, Group VII, transition elements and noble gases.

  1. 8.1

    Arrangement of elements

    Periods, groups, and the link between position and electronic configuration.

    Full lesson1 questions3 cardsReview first: 2.2
    • 8.1.1Describe the Periodic Table as an arrangement of elements in order of proton number.
    • 8.1.2Relate group number to outer-shell electrons and period number to the number of occupied shells.
  2. 8.2

    Group I properties

    The alkali metals: physical properties, reactions with water, and the trend in reactivity.

    Full lesson1 questions3 cardsReview first: 8.1
    • 8.2.1Describe the physical properties and reactions with water of lithium, sodium and potassium.
    • 8.2.2Explain the trend in reactivity down Group I in terms of electron loss.
  3. 8.3

    Group VII properties

    The halogens: colours and states, the trend in reactivity, and displacement reactions.

    Full lesson2 questions4 cardsReview first: 8.1
    • 8.3.1Describe the colours and physical states of chlorine, bromine and iodine and the trend down the group.
    • 8.3.2Describe and explain displacement reactions of halogens with halide solutions.
  4. 8.4

    Transition elements

    Characteristic properties: variable oxidation states, coloured compounds and catalytic activity.

    Full lesson1 questions3 cardsReview first: 8.1
    • 8.4.1Describe the general properties of transition elements compared with Group I metals.
  5. 8.5

    Noble gases

    Group VIII: full outer shells, lack of reactivity, and uses.

    Full lesson1 questions3 cardsReview first: 8.1
    • 8.5.1Explain the lack of reactivity of the noble gases in terms of their electronic configuration.
