Question

write note on radius ratio rule for ionic compound.​

Answer 1

Explanation:

In condensed matter physics and inorganic chemistry the cation-anion radius ratio (also: radius ratio rule) is the ratio of the ionic radius of the cation to the ionic radius of the anion in a cation-anion compound. This is simply given by . ... For radius ratios greater than 0.155, the compound may be stable.
