Ligancy

Ligancy is defined as the number of nearest anions surrounding the central cation.

Critical Radius Ratio:- The ratio of cation radius to the anion radius in an ionic crystal for which the crystal is stable is called the Critical Radius Ratio.

Conditions for stability of ionic crystal:-

  • The stability …
