In this course you will learn exactly what you need to know for your chemistry exams so that you can learn as efficiently as possible.
Understand the three states of matter in terms of the arrangement, movement and energy of the particles
Understand the interconversions between the three states of matter in terms of: the changes in arrangement, movement and energy of the particles.
Understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained
Know what is meant by the terms: • solvent • solute • solution • saturated solution.
Know what is meant by the term solubility in the units g per 100 g of solvent
Understand how to classify a substance as an element, compound or mixture
- Understand how a chromatogram provides information about the composition of a mixture
- Understand how to use the calculation of Rf values to identify the components of a mixture
- Know what is meant by the terms atom and molecule
- Know the structure of an atom in terms of the positions, relative masses and relative charges of sub-atomic particles
- Know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar)
- Be able to calculate the relative atomic mass of an element (Ar) from isotopic abundances
- Understand how to deduce the electronic configurations of the first 20 elements from their positions in the Periodic Table
- Understand how the electronic configuration of a main group element is related to its position in the Periodic Table
- Understand how ions are formed by electron loss or gain
- Know the charges of common ions
- Write formulae for compounds formed between the ions listed above
- Draw dot-and-cross diagrams to show the formation of ionic compounds by electron transfer, limited to combinations of elements from Groups 1, 2, 3 and 5, 6, 7
- Understand ionic bonding in terms of electrostatic attractions
- Understand why compounds with giant ionic lattices have high melting and boiling points
- Know that ionic compounds do not conduct electricity when solid, but do conduct electricity when molten and in aqueous solution
- Know that a covalent bond is formed between atoms by the sharing of a pair of electrons
- Understand covalent bonds in terms of electrostatic attractions
- Understand how to use diagrams to represent covalent bonds in a range of molecules
- Explain why substances with a simple molecular structures are gases or liquids, or solids with low melting and boiling points
- Explain why the melting and boiling points of substances with simple molecular structures increase, in general, with increasing relative molecular mass
- Explain why substances with giant covalent structures are solids with high melting and boiling points
- Explain how the structures of diamond, graphite and C60 fullerene influence their physical properties, including electrical conductivity and hardness
