A-Level Chemistry

Exam Board: OCR A

Why study A-Level Chemistry?

Studying A Level Chemistry will give you insight into the physical universe. Chemistry is often referred to as a central science as it combines physics, biology, mathematics and medicine. Through Chemistry we are able to explain biological and physical phenomena that cannot be understood through one science alone.

What will you study?

1. Atomic structure

2. Mass number and isotopes

3. Electron configuration

4. Relative atomic mass and relative molecular mass

5. The ideal gas equation

6. Empirical and molecular formula

7. Balanced equations and associated calculations

8. Ionic bonding


  • Practical Skills – planning, research, experimental technique
  • Atomic structure – electronic configuration, orbitals and periodicity
  • Properties of substance – bonding, polarity and shapes of molecules
  • Periodic table – group 2, halogens and qualitative analysis
  • Amount of substance – reacting masses, concentration and ideal gas equation
  • Organic chemistry – hydrocarbons, synthetic routes, aromatics and reaction mechanisms
  • Analytical techniques – mass spectrometry, infrared spectrometry and NMR spectrometry
  • Thermodynamics – rates, equilibrium, enthalpy and entropy
  • Physical chemistry – redox, electrode potentials and transition elements

Who is the course suitable for?

If you choose to pursue a career in dentistry, veterinary science, medicine, chemistry-based grades like pharmacology, biochemistry and pharmacy, then chemistry is what are you will need. An A-level in chemistry can also lead to a good salary in later life.
