( r +/ r -)=(88/200)=0.44 so CN is 6 .

Q. The two ions $A^{+}$ and $B^{-}$ have radii $88$ and $200 p m$ respectively. In the closed packed crystal of compound $A B$ , predict the co-ordination number of $A^{+}$ .

$\frac{r ^{+}}{r ^{-}} = \frac{88}{200} = 0.44$
so $CN$ is $6$ .

Q. The two ions A+and B−have radii 88 and 200pm respectively. In the closed packed crystal of compound AB, predict the co-ordination number of A+.

r−r+​=20088​=0.44 so CN is 6 .
