Question:
What is the coordination number of Ag in a crystal lattice?
What is the coordination number of Ag in a crystal lattice?
Show Hint
Silver crystallises in fcc (ccp), which has the highest packing.
Updated On: Oct 1, 2026
- \(4\)
- \(6\)
- \(12\)
- \(8\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Identify the lattice
Silver crystallises in a face centred cubic (cubic close packed) lattice.
Step 2: Coordination number
In ccp or hcp every atom touches \(12\) others, so the coordination number is \(12\). Simple cubic gives \(6\) and bcc gives \(8\), which are the wrong options for silver.
Final Answer:
The coordination number is 12. \[ \boxed{\text{(C)}\ 12} \]
