Most of the points are covered in the Chemical Ideas, with supporting information in the Storyline or Activities. However, if the main source of information is the Storyline or an Activity, this is indicated.

1	The use of the concept of amount of substance to perform calculations involving: masses of substances, empirical and molecular formulae and percentage composition.
2	The procedure for carrying out a titration (Activity EL2.1).
3	Writing balanced chemical equations.
4	The reaction of the Group 2 elements magnesium, calcium, strontium and barium with water.
5	The solubilities of the hydroxides and carbonates of the Group 2 elements.
6	The thermal stability of the carbonates of the Group 2 elements.
7	An outline of the historical development of the Periodic Table (Storyline EL3).
8	The arrangement of the elements in the Periodic Table in terms of atomic (proton) number and common properties.
9	An outline of the periodic trends in the properties of the elements in the Periodic Table ( eg melting point and boiling point, electrical conductivity and ionisation enthalpy).

11	The mass and relative charge of protons, neutrons and electrons.
12	The structure of atoms in terms of protons, neutrons and electrons.
13	The meaning of the terms: atomic number, mass number, isotope, Avogadro constant, relative isotopic mass, relative atomic mass, relative formula mass and relative molecular mass.
14	The use of data from a mass spectrometer to determine relative atomic mass and the relative abundance of isotopes (Activity EL4.2).
15	The principles underlying the operation of a mass spectrometer.
16	The formation of elements in stars by nuclear fusion processes.
17	Absorption and emission atomic spectra (make sure you know the difference).
18	The atomic emission spectrum of hydrogen in terms of changes in electronic energy levels.
19	The meaning of the term: ionisation energy (enthalpy).
20	The nuclei of some a toms are unstable, and these atoms are radioactive.

26	Equations for the first and successive ionisation enthalpies of an element.
27	The use of simple 'dot-cross' diagrams to describe how atoms bond through ionic, covalent and dative covalent bonds.
28	A simple model of metallic bonding.
29	The use of the electron pair repulsion principle to predict the shapes of simple molecules (such as CH4, NH3 and H2O) and ions (such as NH4+).
