Is N2 Symmetrical or Asymmetrical?

The molecule is not symmetric. The nitrogen and hydrogen have different electronegativities, creating an uneven pull on the electrons.

Is H2 asymmetric or symmetrical?

Symmetrical molecules are nonpolar. Because nonpolar molecules share their charges evenly, they do not react to electrostatic charges like water does. Covalent molecules made of only one type of atom, like hydrogen gas (H2), are nonpolar because the hydrogen atoms share their electrons equally.

Is N2 polar?

Nitrogen molecule is a non polar covalent molecule.
