    Ionic bonds occur when a metal and nonmetal bond together to form a compound. Since K is a metal and Br is a nonmetal it forms an ionic bond. The trend for atomic radius decreases as it moves from left to right and since K and Br are on the same row and K is further to the left, K is the largest in the compound. Hope this helps.
