1.	predict the closed packing structure of an ionic compound A+ B- for which radius of cartoon is 148 pm and radius is 195 pm what is coordination number of the cation
Answer» IUS RATIO is USED to FIND the coordination number. Radius of cation = 148 pmRadius of ANION= 195 pmRadius ratio=radius of cationradius of anionradius ratio=148195=0.7589Hence the compound is cubic.Coordination number=8
