Tungsten crystallizes according to BCC unit cell where the edge length of the unit cell is 316.52pm. Use this information to address the following: Use the unit cell edge length to calculate the atomic radius W. How does your answer compare to the known literature value (NOTE: The literature value is 139pm).
FOR BCC:
a*sqrt(3) = 4r
Here:
a is edge length of cube
r is radius of atom
use:
a*sqrt(3) = 4r
316.52 * 1.732 = 4*r
r = 137 pm
% difference from literature value = (139-137)*100/137
= 1.46 %
Answer:
radius = 137 pm
% difference from literature value =1.46 %
