Consider the bcc unit cells of the solids 1 and 2 with the position of atoms as shown below. The radius of atom is twice that of atom The unit cell edge length is 50% more is solid 2 than in 1. What is the approximate packing efficiency in solid 2?
View answer and explanation
Correct option: B
0.9
Option B is correct because the packing efficiency for solid 2 is calculated considering the increased edge length and the doubled radius of atom B. This results in a packing efficiency close to 0.9.
