1umm, the answer doesnt seem to match yaar
someone please help me with this Q:
The maximum radius of an atom which can occupy empty spaces (voids) in a body centred structure, of an element having atomic radius R, without causing any distortion, can be :
Ans, (√53-1)R

1As we know radius ratio for cubic void
i.e., r+/r-=0.732 (without distortion)- 0.999(with distortion)
if R is r-, then maximum radius of r+(which is the radius of cation occupying void) is 0.732 times of R
for metallic solids:
2R + (empty space) = √3a
empty space = √3a - 2R
1hey, is it 0.155 times of R
initially i have calculated for cubic void.....
