Question
Number of tetrahedral voids in the FCC unit cell is
Solution
In a Face Centered Cubic (FCC) unit cell, the number of tetrahedral voids is twice the number of atoms.
Here's the step by step explanation:
- In an FCC unit cell, there are 4 atoms. This is because each corner atom is shared by 8 adjacent unit cells and each face-centered atom is shared by 2 adjacent unit cells. So, the total number of atoms in an FCC unit cell is (1/8)*8 (for the corners) + (1/2)*6 (for the
