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` atoms the cube centres and `R` atoms the edges. The formula of the compound is

Text Solution

Verified by Experts

Number of atoms of P =`8xx1/8`=1
Number of atoms of Q =1 x 1 =1
Number of atoms of R = `6 xx 1/2`=3
hence, compound is `PQR_3`.
