An element crystallises in bcc type crystal structure with edge length of unit cell 300 pm . Calculate radius of element?
Options
- A2 299 10⁻⁸ ~cm
- B1 299 10⁻⁸ ~cm
- C6 920 10⁻⁸ ~cm
- D1 440 10⁻⁸ ~cm
Correct answer
B. 1 299 10⁻⁸ ~cm
Step-by-step solution
a=300 pm =3 10⁻⁸ ~cm For bcc unit cell, r= 3 a 4 r= 1.732 3 10⁻⁸ ~cm 4 =1.299 10⁻⁸ ~cm
