F sub-shells are not examinable at AS or A2.
- Make sure you can write a full Electronic structure for every element up to calcium for AS.
- Make sure you can do the same for the first row of the Transition Block for A2.
- Make sure you can do the same for ions of the above by adding or subtracting electrons according to their charge.
- And finally, make sure you can identifying an element or its ion from its full electronic structure.
The details of how to do most of these are on the electronic structure page.
