A crystal is made up of particals X, Y, ...

A crystal is made up of particals `X`, `Y`, and `Z`. `X` froms `fcc` packing. `Y` occupies all octahedral voids of `X` and `Z` occupies all tetrahedral voids of `X`. If all the particles along one body diagonal are removed. Then the fromula of the crystal would be

A

`XYZ_(2)`

B

`X_(2)YZ_(2)`

C

`X_(6)H_(4)Z_(5)`

D

`X_(5)Y_(4)Z_(8)`

Text Solution

Verified by Experts

No. of X atoms Left =` 4-((1)/(8)xx2) = (15)/(4) `
No. of Y atoms Left `=4-(1xx1)=3`
No. of Z atom Left `=8-(1xx2)=6`
The simplest formula of crystal is `X_(5)Y_(4)Z_(8)`
