`AB` crystallises in a bcc lattice with edge length `qa` equal to `387` pm`.The distance between two oppositely chariged ions in the lattice is

A

335 pm

B

250 pm

C

200 pm

D

300 pm

Text Solution

Verified by Experts

The correct Answer is:
A
Distance between two oppositely charged ions
`(r^(+)+r^(-))=(asqrt(3))/(2)=(387xxsqrt(3))/(2)`
`=335.14` pm
