NO2^-, the nitrite anion, is made with covalent bonds between N and O. It is polar. When combined with a metal atom, it forms an ionic bond, such as in NaNO2.

NO2- has a polar covalent bond due to the difference in electronegativity between nitrogen and oxygen. This creates an unequal sharing of electrons, resulting in a polar molecule.

What is the increasing ordor of electronegativity in ionic bond and polar covalent bond and non polar covalent bond?

The increasing order of electronegativity in bonds is lowest for nonpolar covalent bonds, followed by polar covalent bonds, and highest for ionic bonds. In nonpolar covalent bonds, the electronegativity difference between atoms is minimal, whereas in polar covalent bonds, there is a moderate electronegativity difference leading to partial charges. Ionic bonds have the highest electronegativity difference, resulting in complete transfer of electrons.


Is S and O ionic or covalent?

Polar covalent. The difference in electronegtivity is insufficient for an ionic bond


Is the bond formed between Si and C ionic polar covalent or nonpolar covalent?

The bond formed between Si and C is predominantly covalent. Silicon and carbon have similar electronegativities, so they share electrons fairly equally, resulting in a nonpolar covalent bond.


Is BF3 non polar covalent polar covalent or ionic bond?

BF3 has a nonpolar covalent bond because the electronegativity difference between boron and fluorine is not significant enough to create a polar covalent bond. In a nonpolar covalent bond, electrons are shared equally between the atoms involved.


If two covalently bonded atoms are identical the bond is identified as?

If two covalently bonded atoms are identical, the bond is identified as a nonpolar covalent bond.


Is phenyl salicylate a ionic polar or non polar bond?

Phenyl salicylate has covalent bonds, which are typically nonpolar. The molecule is symmetrical and contains nonpolar functional groups, making it nonpolar overall.


Is SO2 non polar covalent polar covalent or ionic bond?

Polar covalent. The difference in electronegtivity is insufficient for an ionic bond


What is N-O bond type ionic polar covalent nonpolar covalent or metallic?

Polar covalent. Due to the difference in electronegativity between nitrogen (N) and oxygen (O), the bond they form is polar covalent, meaning that the electrons are not shared equally between the atoms.


Is CaI2 polar?

Calcium hydroxide is ionic, and therefore polarity does not occur.


Is MgCl2 a polar covalent non polar covalent or ionic bond?

Magnesium chloride has an ionic bond.


Is a covalent bond considered polar or nonpolar?

A covalent bond can be polar or nonpolar depending on the electronegativity difference between the atoms involved. If the atoms have similar electronegativity, the bond is nonpolar; if there is a difference in electronegativity, the bond is polar.


Does Na and Cl make a polar covalent bond?

No, sodium (Na) and chlorine (Cl) form an ionic bond rather than a polar covalent bond. In an ionic bond, electrons are transferred from one atom to another, leading to a strong electrostatic attraction between the ions.
