Which statement describes the bonds in nitrate (NO3-)?

Question

1. Nitrogen and oxygen have an electronegativity difference of 0.5
, so the bond is ionic.
2. Nitrogen and oxygen have an electronegativity difference of 0.5
, so the bond is polar covalent, with nitrogen pulling the electrons toward it.
3. Nitrogen and oxygen have an electronegativity difference of 0.5
, so the bond is nonpolar covalent.
4. Nitrogen and oxygen have an electronegativity difference of 0.5
, so the bond is polar covalent, with oxygen pulling the electrons toward it.

Answer 1

2. Nitrogen and oxygen have an electronegativity difference of 0.5, so the bond is polar covalent, with nitrogen pulling the electrons toward it.
