The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell. The body-centered cubic (bcc) has a coordination number of 8 and contains 2 atoms per unit cell. The simple cubic has a coordination number of 6 and contains 1 atom per unit cell
A body centered cubic cell (BCC) has coordination number 8. There is one atom at each of the 8 corners, where each atom has 1/8 contribution to the considered unit cell. And, for a BCC unit cell, there is an atom at the centre of the cube, which contributes fully to the unit cell. Hence, in total we get 2 atoms in a BCC unit cell.
(the answer is
hope this helps u
2 atoms are present per unit cell in body center unit cell
The unit cell of body centered cube contains total 2 atoms.
for simple cubic 1
for body centred cubic 2
for face centered cubic 4
Here is ur answer
•It contains two atoms.
•One is at the centre of the cube whereas each 8 corners have 1/8 cell
so total 1/8×8=1
So in bcc type of arrangement total no.of atoms =1+1=2
HOPE THIS HELPS
