The structure of a typical ionic solid - sodium chloride:
How the ions are arranged in sodium chloride
Sodium chloride is taken as a typical ionic compound. Compounds like this consist of a giant (endlessly repeating) lattice of ions. So sodium chloride (and any other ionic compound) is described as having a giant ionic structure.
You should be clear that giant in this context doesn't just mean very large. It means that you can't state exactly how many ions there are.
There could be billions of sodium ions and chloride ions packed together, or trillions, or whatever - it simply depends how big the crystal is. That is different from, say, a water molecule which always contains exactly 2 hydrogen atoms and one oxygen atom - never more and never less.
