Question
The number of carbon atoms per unit cell of diamond unit cell is :-
Options
A.1
B.4
C.8
D.6
Solution
In the diamond cubic unit cell, there are eight corner atoms, six face centered atoms and four more atoms inside at alternate tetrahedralvoids .
∴ Number of atoms present in a diamond cubicunit cell = 1 + 3 + 4 = 8 atoms
∴ Number of atoms present in a diamond cubicunit cell = 1 + 3 + 4 = 8 atoms
