For tetrahedral coordination number, the radius ratio `(r_(c^(+)))/(r_(a^(-)))` is :

A

0.732-1.000

B

0.414-0.732

C

0.225-0.414

D

0.155-0.225

Text Solution

Verified by Experts

The correct Answer is:
C
For tetrahedral arrangement co-ordination number is 4 and radius ratio- `(r_(+)//r_(-))` is 0.225 - 0.414.
