2. In a solid 'AB' having NaCl structure atoms occupy the corners of the cubic unit cell. If all the face centered atoms along one of the axis are removed then the resultant stoichiometry of the solid is ___________?
number of atoms of A in the unit cell = (1/8 * 8) + (1/2* 6) = 4
Number of atoms of B which occupies octahedral voids = 1+ ( 1/4 * 12) = 4
Therefore formula = A4B4 = AB ( Like NaCl)
