A solid has a structure in which

{X}

atoms are located at cubic corners of unit cell,

{O}

atoms are at the edge centers and

{Y}

atoms at cube centre. Then the formula of compound is

{X}_{{a}} {Y}_{{b}} {O}_{{c}}

. If two atoms of

{O}

are missing from any of two edge centers per unit cell, then the molecular formula is

{X}_{{x}} {Y}_{{y}} {O}_z

. Then, find the value of

({x}+{y}+{z})-

(a+b+c)

View answer and explanation

Correct option: A

Option A (4) is correct because the change in the number of oxygen atoms due to the missing atoms at the edge centers affects the overall formula, leading to a difference of 4 in the sum of the subscripts.
