The net charge on the compound should be zero. Or the sum of oxidation states = 0.
Given: oxidation number of X is +2, Y is +5 and Z is -2.
In XYZ

:
2+5+2×(−2)=+3
In Y

)
2
:
2×5+2×(2+3×(−2))=+2
In X

:
3×2+2×(5+4×(−2))=0
In X

:
3×2+2×(4×5−2)=42
A compound contains atoms X, Y and Z . The oxidation number of X is +2 , Y is +5 and Z is -2.
The possible formula of the compound is X
