Electron density contour maps can be used to investigate the transition between purely ionic bonding and covalent bonding.
Aluminium iodide, AlI3AlI_3AlI3, is a compound that exhibits a significant degree of covalent character due to the severe polarisation of the anion by the cation.
Which of the following diagrams best represents the electron density distribution in solid aluminium iodide?
Diagram A
Diagram B
Diagram C
Diagram D
