What is the coordination number of Ag in a crystal lattice?
Options
- A4
- B6
- C12
- D8
Correct answer
C. 12
Step-by-step solution
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
