Solid State Question 241
Question: If the value of ionic radius ratio $ ( \frac{r _{c}}{r _{a}} ) $ is 0.52 in an ionic compound, the geometrical arrangement of ions in crystal is
Options:
A) Tetrahedral
B) Planar
C) Octahedral
D) Pyramidal
Show Answer
Answer:
Correct Answer: C
Solution:
The value of ionic radius ratio is 0.52 which is between $ 0.414-0.732, $ then the geometrical arrangement of ions in crystal is octahedral.
