Chemistry - Solid State Question with Solution | TestHub

Silver (Ag) crystallizes in a face-centered cubic (fcc) or cubic close-packed (ccp) lattice structure.

In an fcc or ccp lattice, each atom is surrounded by $12$ nearest neighboring atoms ($6$ in its own layer, $3$ in the layer above, and $3$ in the layer below).

Therefore, the coordination number of Ag in its crystal lattice is $12$.

Answer: $12$
