  1. 8.1 Arrangement of elements

    1. • Describe Periodic Table as an arrangement of elements in periods and groups and in order of increasing proton number/atomic number

    2. • Describe change from metallic to non-metallic character across a period

    3. • Describe relationship between group number and the charge of the ions formed from elements in that group

    4. • Explain similarities in the chemical properties of elements in the same group of the Periodic Table in terms of their electronic configuration

    5. • Explain how the position of an element in the Periodic Table can be used to predict its properties

    6. • Identify trends in groups, given information about the elements

  2. 8.2 Group I properties

    1. 8.2.1Group I alkali metals, lithium, sodium

      • Describe Group I alkali metals, lithium, sodium and potassium, as relatively soft metals with general trends down the group, (a) decreasing melting point (b) increasing density (c) increasing reactivity

    2. 8.2.2Predict the properties of other

      • Predict the properties of other elements in Group I, given information about the elements

  3. 8.3 Group VII properties

    1. • Describe Group VII halogens, chlorine, bromine and iodine, as diatomic non-metals with general trends down the group, (a) increasing density (b) decreasing reactivity

    2. • State the appearance of the halogens at r.t.p. as: (a) chlorine, a pale yellow-green gas (b) bromine, a red-brown liquid (c) iodine, a grey-black solid

    3. • Describe/explain the displacement reactions of halogens with other halide ions

    4. • Predict the properties of other elements in Group VII, given information about the elements

  4. 8.4 Transition elements

    1. • Describe transition elements as metals that: (a) have high densities (b) have high melting points (c) form coloured compounds (d) often act as catalysts as elements and in compounds

    2. • Describe transition elements as having ions with variable oxidation numbers, including iron(II) and iron(III)

  5. 8.5 Noble gases

    1. • Describe Group VIII noble gases as unreactive, monatomic gases and explain this in terms of electronic configuration
