2. Re: ionic bonding
They want you to draw a 3D representation of the structure, the first statement shows you get 1 mark for the 2D arrangement. Add 3 more ions (so that 7 altogether are visible...or more) in a different plane to get the remaining mark.
3. Re: ionic bonding
Would this be right ?? (see second picture that I've attatched) ...is there any particular reason why they want you to do it 3d in the mark scheme?

Essentially because AgF exists as a giant ionic lattice, which has a 3 dimensional structure, so you have to show the ionic lattice as being 3 dimensional.

And yeah, but just make it a bit neater, and without the cubic lines
