If the value of ionic radius ratio

\left( {\frac{{{r_c}}}{{{r_a}}}} \right)

is 0.52 in an ionic compound, the geometrical arrangement of ions in crystal is

View answer and explanation

Correct option: D

Octahedral

Option D (Octahedral) is correct because an ionic radius ratio of 0.52 falls within the range (0.414 - 0.732) that corresponds to an octahedral arrangement.
