The tatio of the cationic radius to anionic radius in an ionic crystal

1.	The tatio of the cationic radius to anionic radius in an ionic crystal is greater than 0.732. Its co-ordination number is
Answer» 1 4 6 8 Solution :When radius RATIO`r^(+)//r^(-)gt0.732`, the cation is PRESENT at the CUBIC side in a simple cubic lattice of anions. The co-ordination NUMBER of cation =co-ordination number of anion=8
