A solid has a ' b c c ' structure. If the distance of nearest approach between two atoms is 1.73 Å , the edge length of the cell is

Options

  1. A314.20 pm
  2. B1.41 pm
  3. C200 pm
  4. D216 pm

Correct answer

C. 200 pm

Step-by-step solution

For bcc structure d= 3 a 2 where d= distance between two atoms a= edge length aligned & 1.73= 3 2 a & a= 2 1.73 3 =2 Å=200 pm aligned
