Question

What is the coordination number of Ag in a crystal lattice?

• A. \(4\)
• B. \(6\)
• C. \(12\)
• D. \(8\)

Hint:

Silver crystallises in fcc (ccp), which has the highest packing.

Answer 1

The Correct Option is C

Step 1: Recall
Silver is fcc, a close packed structure. Close packed structures have coordination number 12.

Step 2: Answer
Option (C).

Final Answer:
12. \[ \boxed{\text{(C)}\ 12} \]
