Question

In crystal lattice formed by bcc unit
cell the void volume is
a. 68 %
b. 74%
c.32 %
d. 26%​

Answer 1

Answer:

A.68%

Explanation:

Answer 2

In crystal lattice formed by bcc unitcell the void volume is c) 32%.

• The crystal formed by atoms, ions and molecules constitutes the complete crystal lattice.
• The unit cell is formed by dividing the crystal lattice into blocks.
• Lattice are of many types such as body centred cubic, cubic closed packing, face centred cubic and square closed packing etc.
• The volume occupied by a time in the bcc unit cell is 68%. so, the volume occupied by void is 100-68 = 32%.
• The volume occupied by atoms in the fcc unit cell is 74% and the volume occupied by atoms in the ccp unit cell is 52%.
