Calculate the edge length of bcc unit cell if radius of a particle present in it is 186 pm .
- A \(4.296 \times 10^{-8} \mathrm{~cm}\)
- B \(7.301 \times 10^{-8} \mathrm{~cm}\)
- C \(3.715 \times 10^{-8} \mathrm{~cm}\)
- D \(5.419 \times 10^{-8} \mathrm{~cm}\)
Answer & Solution
Correct Answer
(A) \(4.296 \times 10^{-8} \mathrm{~cm}\)
Step-by-step Solution
Detailed explanation
\(a = \frac{4r}{\sqrt{3}}\) \(a = \frac{4 \times 186 \text{ pm}}{\sqrt{3}} \approx 429.55 \text{ pm}\)
