Review the information.
In Compound A, Element W has an electronegativity of 2.8, and Element X has an electronegativity of 2.5.
In Compound B, Element Y has an electronegativity of 2.0, and Element Z has an electronegativity of 3.8.
Which statement correctly identifies the ionic compound and describes the use of electronegativity in determining this?
A. Compound A is ionic. The electronegativity difference is 5.3, which can be determined by adding the electronegativity of Element W to Element X. Electronegativity differences greater than 1.7 indicate ionic bonds.
B. Compound B is ionic. The electronegativity difference is 1.8, which can be determined by subtracting the electronegativity of Element Y from Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.
C. Compound A is ionic. The electronegativity difference is 0.3, which can be determined by subtracting the electronegativity of Element X from Element W. Electronegativity differences less than 1.7 indicate ionic bonds.
D. Compound B is ionic. The electronegativity difference is 5.8, which can be determined by adding the electronegativity of Element Y to Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.
I think it is B
