Three elements P,Q and R crystallize in ...

Three elements `P,Q` and `R` crystallize in a cubic solid lattice. The `P` atoms occupy the corners. `Q` aroms the cube centres and `R` atoms the edges. The formula of the compound is

A

`PQR`

B

`PQR_(2)`

C

`PQR_(3)`

D

`PQ_(3)R`

Text Solution

Verified by Experts

The correct Answer is:
3
`P=8xx(1)/(8)=1,Q=1=1,R=12xx(1)/(4)=3,`formula`=PQR_(3)`
