If the edge length of a bcc unit cell is 300 pm . Calculate the body diagonal.

Options

  1. A600 pm
  2. B423 pm
  3. C519.6 pm
  4. D450.4 pm

Correct answer

C. 519.6 pm

Step-by-step solution

For a cubic unit cell, the length of the body diagonal is given by 3 a , where a is the edge length of the unit cell. Given a = 300 pm . Body diagonal = 3 300 pm Substituting 3 1.732 : Body diagonal = 1.732 300 pm = 519.6 pm Answer: 519.6 pm
