AB crystallizes in a body centred cubic ...

`AB` crystallizes in a body centred cubic lattice with edge length `a` equal to `365p m` .The distance between two oppositely charged ions in the lattice is :

A

335 pm

B

316 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^(-))`
`2(r^(+)+r^(-))=sqrt(3)a`
`(r^(+)+r^(-))=(sqrt(3)a)/2=(sqrt(3)xx387 "pm")/2=335"pm"`
