The co-ordination number of zinc in zinc blende (Zns) is

A

4

B

6

C

2

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
In ZnS, `S^(2-)"ions adopt f.c.c. lattice in which " Zn^(2+)" ions are present in alternate tetrahedral sites "`.
`therefore" Co-ordination number of " S^(2-) = " Co-ordination number of " Zn^(2+) = 4`
