The link between the same atom is always non-polar Covalent.Is Covalent because there is no possibility of an atom donating electrons to the other, since they are equal and need the same number of electrons, and is why the formal charge non-polar (electronegativity) of two atoms is equal. When there is no difference of formal charges (dipole moment) between the atoms, the connection is always apolar.

Explanation:
Hello there!
In this case, according to the given information, it turns out possible to set up the initial version of the half-reaction as follows:
Now, we assign the oxidation numbers to both nitrogen atoms:
It means three electrons are carried, two water molecules are needed on the left side in order to balance the oxygen atoms and consequently four hydronium ions to balance hydrogen atoms in acidic media:
