In a face centred cubic arrangement of metallic atoms, what is the relative ratio of the sizes of tetrahedral and octahedral voids ?

A

`0.543`

B

`0.732`

C

`0.414`

D

`0.637`

Text Solution

Verified by Experts

The correct Answer is:
1
`(r_("tetrahedral"))/(r_("octahedral"))=(0.225R)/(0.414R)=0.543`
