For BCC unit cell the edge length is `27A^@`. Find the edge length of the same unit cell in FCC arrangement.

In the body-centred cubic unit cell and face centred cubic unit cell, the radius of atom in terms of edge length(a) of the unit cell is respectively:

A certain element crystallises in a bcc lattice of unit cell edge length 27Å. If the same element under the same conditions crystallises in the fcc lattice, the edge length of the unit cell in Å will - (Round off to the Nearest Integer). [Assume each lattice point has a single atom] [Assume sqrt3 =1.73, sqrt2=1.41]

In the body centered cubic unit cell and simple unit cell, the radius of atoms in terms of edge length (a) of the unit cell is respectively:

In a face- centred cubic unit cell, the edge length is

Sodium metal exits in bcc unit cell .The distance between nearest sodium atoms is 0.368 nm. The edge length of the unit cell is:

Select the correct statements among following : (a=edge length of unit cell)

A metal can be crystallized in both BCC and FCC unit cells whose edge lengths are 2 pm and 4 pm respectively. Then ratio of densities of FCC and BCC unit cells is
