Dear studnet 
It has zero dipole moment. Two N atoms in nitrogen molecule have zero electronegativity difference. The bond pairs of electrons are equally distributed between two N atoms. So, Nitrogen molecule is non polar. 
 
						

							
Nitrogen molecule is a non-polar covalent molecule. It has zero dipole moment. Two N atoms in nitrogen molecule have zero electronegativity difference. The bond pairs of electrons are equally distributed between two N atoms. true
