# Nitrogen Covalent Bonds

Let me premise this with the fact that I really have zero knowledge of chemistry. So bear with me and my ignorance. :)

Now, with that introduction out of the way, I've read up this site which presented in a very easy to understand way, how a Nitrogen atom bonds to yet another Nitrogen atom to make a fairly common element $\ce{N2}$.

Continuing, it says on that site that when you create $\ce{N2}$ from two Nitrogen atoms, that's as far as you can go for creating covalent bonds between Nitrogen atoms.

Armed with that knowledge, my question is as follows:

- Can you create further bonds utilizing another atom and still keep the strength of a triple bond and $\ce{N2}$'s natural inertness?

• In short: no. The addition of further electrons into the $\ce{N2}$ molecule actually weakens the attachment of the bond(s) between the two atoms, and renders the ensemble charged. For nitrogen, the octet rule is obligatory (en.wikipedia.org/wiki/Octet_rule). – Buttonwood Jul 4 '17 at 20:20
• Well, you can make N2O for example, it isn't as N2 though. – Mithoron Jul 5 '17 at 15:51

Nitrogen atom has 5 electrons in its outer shell. The most stable electronic configuration, by octet rule, corresponds to 8 electrons in outer shell. Nitrogen needs three electrons to make that shell full. It can achieve that configuration by bonding with another nitrogen. One nitrogen has his own 5 electrons and another lends him his 3 - now first nitrogen has 8 electrons, e.g. full shell. First nitrogen lends his 3 electrons to second nitrogen which also had 5 electrons, so now both of them have closed shell. Since both of them lended three electrons, and accepted three - they have three shared electron pairs, which corresponds to triple covalent bond. Closed shell configuration, which they both now achieved, corresponds to a state of the lowest energy. Since everything in nature strives to a state of lowest energy, you can see why $\ce{N}$ atoms prefer to bond, instead of being each on it's own. The molecule is inert, because it achieved what it strived to: energy minimum. By adding another (third) nitrogen in a game, you would necessary have to "break" closed shell configuration, which necessary leads to increase of energy, which is not favorable. That's the reason why you can't create another bond and keep inertness of $\ce{N2}$ molecule.
