AS3.4 Particles and Thermochemistry
This externally assessed standard is worth 5 credits and is essential for
your future understanding at a tertiary level.
You will cover a large amount of content and the teaching  component will take
approximately 10 weeks of class time.

The following is a comprehensive list of all the key areas that you must cover for AS3.4. This topic will introduce a lot of new terminology and concepts, so listen well and ask plenty of questions.

what you need to know!

Properties of particles are limited to:

  • electron configuration of atoms and ions of the first 36 elements (using s,p,d notation)
  • periodic trends in atomic radius, ionisation energy, and electronegativity, and comparison of atomic and ionic radii
  • Lewis structures and shapes (up to six electron pairs about the central atom for molecules and polyatomic ions, including those with multiple bonds), polarity of molecules
  • attractive forces between atoms, ions, and molecules.  These will include ionic bonds, covalent bonds, and intermolecular attractions due to temporary dipoles and permanent dipoles (including hydrogen bonding). 

Properties of substances are limited to:

  • melting point, boiling point and solubility
  • enthalpy and entropy changes associated with spontaneity in chemical reactions (entropy calculations are not required). 

Thermochemical principles include:

  • specific heat capacity
  • phase changes
  • ΔcH°, ΔfH°, ΔrH°, ΔvapH°, ΔsubH°, and ΔfusH°
  • Hess’s Law including application of ΔrH = fH((products) – fH(reactants)) and related calculations.
