Question

According to the standard limiting Radius Ratio Rule ($\frac{r_{	ext{cation}}}{r_{	ext{anion}}}$) in ideal ionic crystals, which of the following geometric boundaries are matched correctly with their resulting coordination number (C.N.)?

Prashant Kotian · Accepted Answer

Correct answer: A,B,C,D. All given ranges match the standard geometric derivation for the limiting radius ratio rule, governing the size limits before a cation forces a transition into a higher coordination polyhedra to maintain stability.
