Vedclass · Answer

(B) In a face-centered cubic $(FCC)$ lattice,each face of the unit cell is shared equally by $2$ adjacent unit cells.However,the question asks about the number of unit cells sharing a face. In a crystal lattice,any given face of a unit cell is common to $2$ unit cells.If the question implies the coordination number or the number of faces,it would be different,but for the sharing of a face,the answer is $2$.

In a face-centered cubic lattice,a unit cell face is shared equally by how many unit cells?
