I can't see the pictures you have — could you upload the image of the models or describe them (colors, how many and how they're arranged)?
How to tell which one is RbBr:
- RbBr is an ionic compound made of Rb+ and Br−, so the correct model will show two different kinds of particles (two colors/sizes) arranged as an ionic pair or in an ionic lattice (alternating ions).
- It will not be a model showing only one kind of atom (that would be an element like Rb or Ag).
- It will not be a diatomic molecule (Cl2 or Br2) which shows two identical atoms bonded together.
If you upload or describe the models I’ll pick the correct one.
