Question

An ionic crystal lattice has r⁺/r⁻ radius ratio of 0.524. its coordination number is
a) 2
b) 4
c) 6
d) 8

Answer 1

6 is the answer. That is 3rd option is correct. It is in tetrahedral void.

Answer 2

An ionic crystal lattice has r⁺/r⁻ radius ratio of 0.524. its coordination number is 6 . because it has tetrahedral void.

It is commonly formed at the time of the one sphere which is placed in the depression formed by the three particles.

Hope this answer provide clear idea to solve your common problem.
