A ball and stick model is used to represent the structure of sodium chloride.
What is one limitation of this model?
It does not show that there are two different types of ion present.
It does not show the ions in a regular, repeating 3D arrangement.
It does not show the ratio of sodium ions to chloride ions in the lattice.
It shows sticks between ions, but ionic bonding acts in all directions.
