If three elements X, Y and Z crystallize...

If three elements X, Y and Z crystallize in a cubic solid with X atoms at the corners, Y atoms at the cube centres and Z atoms at the face of the cube, then write the formula of the compound.

Text Solution

Verified by Experts

Atoms P per formula cell =` 8 xx 1//8 =1 ` , Atoms Q per unit cell =1 , Atoms R per unit cell =1 , Atoms R per unit cell = ` 6 xx 1//2 =3`
Hence the formula is ` PQR_(3)`
