Which of these descriptions match the physical structure of an ionic compound?

• Ions are tightly packed but rotate and move around, creating an amorphous solid.

• Ions form a pattern with local regions consisting only of positive or negative ions, although the overall charge is zero.

• Ions form a regular repeating pattern.

• The pattern of ions results in a balance between the forces of attraction and repulsion.

• Ions exist in a ratio that results in an overall charge of zero for the compound.
