An element crystallises in bcc type having atomic radius 1 33 10⁻⁸ ~cm , the edge length of unit cell will be
Options
- A2 17 10⁻⁸ ~cm
- B2 66 10⁻⁸ ~cm
- C4.08 10⁻⁸ ~cm
- D3 07 10⁻⁸ ~cm
Correct answer
D. 3 07 10⁻⁸ ~cm
Step-by-step solution
For bcc crystal, r = 3 4 a a= 4 r 3 = 4 1.33 10⁻⁸ ~cm 1.732 a=3.07 10⁻⁸ ~cm .
