A certain element crystallises in a bcc lattice of unit cell edge, length 27ºÅ. If the same element under the same conditions crystallises in the fcc lattice, the edge length of the unit cell in Å will be………. (Assume each lattice point has a single atom)

[Assume \( \sqrt3 = 1.73, \sqrt2 = 1.41\)]

Answer: 33

Explanation::

for bcc structure \(4r=\sqrt3a\)

\(r={\sqrt3a\over4}\) …1

For FCC structure \(4r=\sqrt2a\)

\(r={\sqrt2a\over4}\) …2

From 1 and 2
