An element has a body centered cubic (bcc) structure with a cell edge of 288   pm . The atomic radius is
Options
- A2 4 × 288   pm
- B4 3 × 288   pm
- C3 2 × 288   pm
- D3 4 × 288   pm
Correct answer
D. 3 4 × 288   pm
Step-by-step solution
Body-centered cubic (BCC) is the name given to a type of atom arrangement found in nature. A body-centered cubic unit cell structure consists of atoms arranged in a cube where each corner of the cube shares an atom and with one atom positioned at the center. 3 a = 4 r (for bcc lattice) r = 3 4 × 288   pm
