Is NO a polar molecule?

Electronegativity values are useful in determining if a bond is to be classified as nonpolar covalent, polar covalent or ionic. The electronegativities of oxygen and nitrogen are respectively, 3.44 and 3.04 on Pauling scale, the electronegativity difference being, 0.4. The bond is considered to be non-polar covalent.
IF IT HELP U PLZ PICK AS BEST TNX:)

Non - polar molecules occurs when the election sharing during a convalent bond is equal, so there is no ionic charge and the electrons are disturbed symmetrically.
