Question

Calculate the percentage efficiency of packing in case of boby centered cubic crystal​

Answer 1

Explanation:

For simple cubic metal crystal the efficiency of packing = 52.4%. (b) Body centred cubic: From the figure it is clear that the atom at the centre will be in touch with other two atoms diagonally arranged and shown with solid boundaries. Hence, for face centred cubic, efficiency of packing = 74%.
