Which statement describes the bonds in nitrate (NO3-)? (1 point) Responses Nitrogen and oxygen have an electronegativity difference of 0.5 , so the bond is polar covalent, with nitrogen pulling the electrons toward it. Nitrogen and oxygen have an electronegativity difference of 0 point 5, so the bond is polar covalent, with nitrogen pulling the electrons toward it. Nitrogen and oxygen have an electronegativity difference of 0.5 , so the bond is nonpolar covalent. Nitrogen and oxygen have an electronegativity difference of 0 point 5, so the bond is nonpolar covalent. Nitrogen and oxygen have an electronegativity difference of 0.5 , so the bond is polar covalent, with oxygen pulling the electrons toward it. Nitrogen and oxygen have an electronegativity difference of 0 point 5, so the bond is polar covalent, with oxygen pulling the electrons toward it. Nitrogen and oxygen have an electronegativity difference of 0.5 , so the bond is ionic.
