In a solid AB having NaCl structure, 'A' atoms occupy the corners of the cubic unit cell.If all the face-centered atoms along all axes are removed, then the resultant stoichiometry of the solid is :
Answer & explanation
Correct answer: option 1
In Final step, after removing face centred atoms, there are only 8 corner atom which will contribute 8 X ⅛ = 1 A atom and B atoms are 1 + 12 x ¼ = 4 so its AB4
