`AB` crystallizes in a body centred cubic lattice with edge length `a`

1.	`AB` crystallizes in a body centred cubic lattice with edge length `a` equal to `387p m` .The distance between two oppositely charged ions in the lattice is :A. 300pmB. 335pmC. 250pmD. 200pm
Answer» Correct Answer - B For BC C `r^(+)+r^(-)=sqrt(3a)/(2)therefore r^(+)r^(-)=(sqrt(3)xx387)/(2)` pm `=335.14` pm=335pm
