The fraction of total volume occupied by atoms in a simple cube isA. `(pi)/(2)`B. `(sqrt(3)pi)/(8)`C. `sqrt(2pi)/(6)`D. `(pi)/(6)` |
Answer» Correct Answer - d In simple cubic arrangement no of atoms `= 1` `a = 2r` `:.` packing fraction `= ("Volume occupied by one atom")/( "Volume of unit cell")` `((4)/(3) pi r^(3))/(a^(3)) = ((4)/(3) pi r^(3))/((2r)^(3)) = (pi)/(6)` |
