1.	The unit cube Length for LICL (NACL structure) is 5.14 Å. Assuming anion-anion contact, calculate the ionic radius for chloride ion.
Answer» Solution :Interionic DISTANCE of LICL=`5.14/2`=2.57 Å `THEREFORE BC=sqrt(AB^2+AC^2)=sqrt((2.57)^2+(2.57)^2)=3.63` RADIUS of `Cl^-` ion=`1/2` x 3.63 Å =1.81 Å
