Assuming atoms of radius of 1.00脜 and atoms just touching one another, calculate the percentage of the volume

Assuming atoms of radius of 1.00脜 and atoms just touching one another, calculate the percentage of the volume taken up in a simple cubic unit cell by those atomsAssuming atoms of radius of 1.00脜 and atoms just touching one another, calculate the percentage of the volume
in each SC unit cell we have 1 atomic cluster (here just 1 atom) so,



atom volume: 4/3*Pi*r^3=4*Pi/3 脜^3

cell volume: (2脜)^3= 8 脜^3



Packing Factor=(4*Pi/3)/(8)=Pi/6=0.5236
