Question

Coordination number of Zn in ZnS is

• A. 4
• B. 6
• C. 2
• D. None of these

Hint:

ZnS has tetrahedral coordination with coordination number 4.

Answer 1

The Correct Option is A

Step 1: Conceptual Understanding:
ZnS has zinc blende structure.
Step 2: Explanation in Detail:
In ZnS (zinc blende structure), each Zn$^{2+}$ is surrounded by 4 S$^{2-}$ ions. Coordination number is 4.
Step 3: Therefore, Stating the Final Answer
Coordination number is 4.
