Nitrogen.
Oxygen is the most common element in Earth's atmosphere after nitrogen.
Nitrogen is!
The two most similar bonds in polarity are the C-O bond and the C-N bond. Both bonds involve a carbon atom and a more electronegative element (oxygen or nitrogen), resulting in a polar covalent bond with a partial negative charge on the oxygen or nitrogen atom and a partial positive charge on the carbon atom.
Fluorine is the most electronegative element among nitrogen, oxygen, carbon, and fluorine. It has the highest electronegativity value on the periodic table.
Oxygen is an element, not a bond. It will form polar bonds with most other elements, though because it is very electronegative. However, when it bonds with itself as in O2 the bonds are nonpolar.
The air (on ground level, not in a traffic jam!) is composed of ~80% N2, ~20% O2, 0-6% H2O (vary a lot), 0.03% CO2, 1% argon and then traces of other elements. The most abundant element is thus nitrogen N.

Nitrogen
The most abundant element in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant element in the air, at around 21%.
