How many particles per unit cell are present in BCC structure?
- A 1
- B 4
- C 3
- D 2
Answer & Solution
Correct Answer
(D) 2
Step-by-step Solution
Detailed explanation
In BCC structure atoms are present at each corner and at body centre of unit cell.
\(
\text {No. of atoms per unit cell }(Z)=\)\(\underbrace{8 \times \frac{1}{8}}_{\text {coner atoms }}+\underbrace{1 \times 1}_{\text {centreatoms}}\)
\(=2\)
\(
\text {No. of atoms per unit cell }(Z)=\)\(\underbrace{8 \times \frac{1}{8}}_{\text {coner atoms }}+\underbrace{1 \times 1}_{\text {centreatoms}}\)
\(=2\)
