Chemistry - A level

Year 12 

Term Topics taught and learning outcomes
Term 1.1
  • Understand atomic structure and be able to work out numbers of protons, electrons and neutrons in atoms and ions. Apply this knowledge to isotopes.
  • Define key terms, such as relative isotopic mass and use mass spectrometry to determine relative isotopic masses and relative atomic masses.
  • Understand how to calculate the moles of a solid, liquid and a gas. Applying your knowledge to new situations.

ASSESSMENT

End of topic test on everything covered in term 1.1.

HOMEWORK

Calculating the moles of solids, liquids and gases. There will be a homework covering each area.

Term 1.2
  • Understand the definition of an acid and a base and how to represent a neutralisation reaction in terms of ions.
  • Know how to complete acid-base titrations and apply your knowledge to calculate the concentration of the unknown acid.
  • Understand the rules for calculating oxidation numbers of elements, compounds and ions. Apply this knowledge to interpret reactions in terms of oxidation and reduction.

ASSESSMENT

End of topic test covering everything covered in term 1.2.

HOMEWORK

Calculations homework - variety of different ones.

Term 2.1
  • Understand how to show the electronic configuration of any given element in the periodic table, using the rules of orbitals and sub-shells.
  • Demonstrate your understanding of ionic and covalent bonding. Explain the properties of compounds containing this bonding by linking it back to their structure. Recall the shapes of molecules and ions.
  • Recall what electronegativity is and apply this knowledge to explain the various different intermolecular forces.

ASSESSMENT

End of topic test covering everything covered since the beginning of the year so far.
Mock exam.

HOMEWORK

Electronic configuration homework task. 
Bonding homework tasks.
Intermolecular forces homework tasks.

Term 2.2
  • Understand and interpret the periodic table. In particular looking at group 2 and 7 and their reactions.
  • Understand that reactions are accompanied by enthalpy changes that are exothermic or endothermic. Know how to calculate enthalpy changes using bond enthalpies and Hess' cycles.
  • Recall the 4 different ways rates of reactions can be altered. Understand the role of a catalyst in the lab and in industry. Create a Boltzmann distribution to represent the rate of a reaction and how it changes when the temperature is changed and when a catalyst is used.
