A solid has a structure in which W atoms are located at the corners of the cubic lattice, O atoms at the centre of the edges and Na atom at the centre of the cube. The formula of the compound is

Text Solution

Verified by Experts

The correct Answer is:
`NaWO_3`
No. of W atoms = `8 xx 1//8 = 1`
No. of O atoms = `12 xx 1/4 = 3`
No. of Na atoms = 1
Formula = `NaWO_3`.
