I'll describe what you need to draw. Since KI is an ionic compound, the one valence electron that potassium has was transferred to iodine.

On the left, draw a capital letter K+.

On the right, draw a large pair of square brackets. Inside those brackets, draw a capital letter I-. Surround that letter with four pairs of dots (eight total).
