How are edge length 'a' of the unit cell and radius ' r ' of the sphere related to each other in ccp structure? (Choose correct option for your answer.)

Options

  1. Aa=4 r / 3
  2. Ba=2 2 r
  3. Ca=2 r
  4. Da=r / 2 2

Correct answer

B. a=2 2 r

Step-by-step solution

For a ccp structure, 4 r=a 2 a= 4 r 2 a=2 2 r
