The number of octahedral and tetrahedral...

The number of octahedral and tetrahedral sides in a cubical closed packed array of `N` spheres respectively is

A

`N and 2N`

B

`N//2 and N`

C

`2N and N`

D

`4N and 2N`

Text Solution

Verified by Experts

The correct Answer is:
a
Number of octabedral sites = numer of sphares in packing
Number of octabedral volts `2= xx` numer of sphares in packing
Number of octabedral volts `2= xx` oculadral volts so, the answer is `N and 2N`.
