1.	In the compound AX, the radius ofA^(+)ion is 95 pm and that ofX^(-) ion is 181 pm. Predict the crystal structure of AX and write the coordination number of each of the ions.
Answer» SOLUTION :Radius ratio m ` r_(+) //r_(-) = ` 95/181 = 0.525 which in the range0.414- 0.732 . HENCE , the structure is octahedral and COORDINATION NUMBER is 6.
