Question

For AX ionic crystal to exist in bcc structure, the ratio of

• A. between 0.41 to 0.73
• B. greater than 0.73
• C. less then 0.41
• D. None of these

Answer 1

The correct option is B greater than 0.73

For bcc structure, the radius ratio should be greater than 0.73, because radius ratio for bcc structure lies between 0.732 to 1.00.
