Question

For K+ and Br find the radius ratio of K+ ion to Br ion and on this basis predict (5) the shape of crystal geometry of KBr. Draw a diagram indicating the arrangement of K+ and Br ions in the crystal of KBr.? Please Give me full solution

Answer 1

geometry in attachment

K+/Br--ratio is 152 pm/182pm = 0.835. Thus, it should be cubic structure with CN =8
