Calculate the edge length of unit cell of metal which crystallises to bcc structure. (Radius of metal atom =173 pm )
Options
- A5.01 10⁻⁸ ~cm
- B4.00 10⁻⁸ ~cm
- C4.5 10⁻⁸ ~cm
- D5.5 10⁻⁸ ~cm
Correct answer
B. 4.00 10⁻⁸ ~cm
Step-by-step solution
For bcc unit cell, r= 3 4 a aligned a = 4 r 3 = 4 173 1.73 & =400 pm & =400 10⁻¹⁰ ~cm & =4.00 10⁻⁸ ~cm aligned
