If the radius of an atom of an elements ...

If the radius of an atom of an elements is `75` pm and the lattice type is body-centred cubic, what is the edge length of the unit cell?

Text Solution

Verified by Experts

For `BC C, r = (sqrt3)/(4)a`
or `a = (4r)/(sqrt3) = (4 xx 75)/(1.732) = 173.2` pm
