Topics Tested

1. Atomic structure

1.3. Electrons, energy levels and a...

determine the electronic configuration of atoms and ions given the atomic or proton number and charge, using either of the following conventions: e.g. for Fe: \( 1s^2 2s^2 2p^6 3s^2 3p^6 3d^6 4s^2 \) (full electronic configuration) or \( [Ar] 3d^6 4s^2 \) (shortband electronic configuration)

3. Chemical bonding

3.7. Dot-and-cross diagrams

use dot-and-cross diagrams to illustrate ionic, covalent and coordinate bonding including the representation of any compounds stated in 3.4 and 3.5 (dot-and-cross diagrams may include species with atoms which have an expanded octet or species with an odd number of electrons)
