In radius ratio rules, we assume that cations and anions always touch each other.
What do we mean by radius ratio?
Do all the radius ratio rules hold in the case given below?
Assume the blue spheres are anions and red is cation.
What is the use of radius ratios?
In an ionic solid r(+) = 1.6 and r(-) = 1.864 . Use the radius ratio rule to determine the edge length of the cubic unit cell in .
