Can someone please help me with this?--20 pts! In Compound A, Element W has an electronegativity of 3.0, and Element X has an electronegativity of 2.0.
In Compound B, Element Y has an electronegativity of 1.2, and Element Z has an electronegativity of 3.4.
Which statement correctly identifies the ionic compound and describes the use of electronegativity in determining this?

Compound B is ionic. The electronegativity difference is 2.2, which can be determined by subtracting the electronegativity of Element Y from that of Element Z. Electronegativity differences greater than 1.7 indicate ionic bonds.

Compound B is ionic. The electronegativity difference is 4.6, which can be determined by adding the electronegativity of Element Y to that of Element Z. Electronegativity differences less than 5.0 indicate ionic bonds.

Compound A is ionic. The electronegativity difference is 5.0, which can be determined by adding the electronegativity of Element W to that of Element X. Electronegativity differences greater than or equal to 5.0 indicate ionic bonds.

Compound A is ionic. The electronegativity difference is 1.0, which can be determined by subtracting the electronegativity of Element X from that of Element W. Electronegativity differences less than 1.7 indicate ionic bonds.
