The A^(+) ion and B^(-) have radii 88 pm and 200 pm respectively. In the close packed crystal of compound AB, predict the coordination number of A^(+). |

Answer» SOLUTION :In the compound AB, A+ ions occupy the close packed lattice formed by `B^(-)`ions. The radius RATIO is: `(r^(+))/(r^(-))= (88)/(200)= 0.44` Since radius ratio LIES between 0-414 to 0.732. `:.` Co-ordination of `A^(+) = 6` |
