The contribution of particle at the edge centre to a particular unit cell is
- A \( \frac{1}{2} \)
- B \( \frac{1}{4} \)
- C \( 11 \)
- D \( \frac{1}{8} \)
Answer & Solution
Correct Answer
(B) \( \frac{1}{4} \)
Step-by-step Solution
Detailed explanation
The contribution of particle at the edge center to a particular unit cell is \( 1/4 \) as if an atom is present in the edge center it
is shared by four unit-cells, that is, \( 4 \) cubes.
