Reaction conditions, O2, energy etc

There are more

N2O, NO, N2O3, NO2, N2O4 and N2O5

It's the matter of oxidation stage of nitrogen. It is from +1 to +5 possible.

Edited August 22Aug 22 by chenbeier

The Wikipedia article "Nitrogen oxide" lists the following:

• Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide

• Nitrogen dioxide (NO₂), nitrogen(IV) oxide

• Nitrogen trioxide (NO₃), or nitrate radical

• Nitrous oxide (N₂O), nitrogen(0,II) oxide

• Dinitrogen dioxide (N₂O₂), nitrogen(II) oxide dimer

• Dinitrogen trioxide (N₂O₃), nitrogen(II,IV) oxide

• Dinitrogen tetroxide (N₂O₄), nitrogen(IV) oxide dimer

• Dinitrogen pentoxide (N₂O₅), nitrogen(V) oxide, or nitronium nitrate [NO₂]⁺[NO₃]⁻

• Nitrosyl azide (N₄O), nitrogen(−I,0,I,II) oxide

• Nitryl azide (N₄O₂)

• Oxatetrazole (N₄O)

• Trinitramide (N(NO₂)₃ or N₄O₆), nitrogen(0,IV) oxide

Some of these have somewhat complicated structures.

It's worth noting that the electron configuration of nitrogen is [He] 2s² 2p³. This means that nitrogen can donate up to 5 electrons and accept up to 3 electrons. Note that chemical bonding usually involves both donating electrons to the atoms to which it is bonded and accepting electrons from those atoms. Thus, donating up to 5 and accepting up to 3 electrons impacts on the possible structures that nitrogen can form. Contrast this with phosphorus whose electron configuration is [Ne] 3s² 3p³. Again, this can donate up to 5 electrons, but with empty 3d orbitals available to accept electrons, expanding the octet allows phosphorus to have structures that are not available to nitrogen.

Great you found more exotic NxOy compounds.

Question is how multiple molecules are possible with different atom ratio ? Do they leave lone electrons ? I don't get the math is it some other phenomenon ?

The math is following Example hydrocarbons . They have infinite compounds.

First group are alkane.

CnH2n+2, n = €N0

With n =1 you get CH4 Methane

And so one.

There are more groups

@HbWhi5F

Different elements have different electron configurations,

https://en.wikipedia.org/wiki/Electron_configuration

meaning that their electron shells and subshells are filled differently.

https://en.wikipedia.org/wiki/Electron_shell

The force of attraction of these electrons varies, which means that different amounts of energy are required to eject them or move them to a higher energy level.

https://en.wikipedia.org/wiki/Ionization_energies_of_the_elements_(data_page)

To understand why nitrogen and oxygen form these compounds from your list, you need to understand what electron configurations, electron shells, and subshells are.

From a simpler note, are you familiar with the octet rule?

https://en.wikipedia.org/wiki/Octet_rule

Your dataset suggests that the only chloride and oxygen molecule is Cl2O7, but that is not true.

https://en.wikipedia.org/wiki/Dichlorine_trioxide

Cl2O3

https://en.wikipedia.org/wiki/Dichlorine_monoxide

Cl2O

etc.

If that were true, then long before reaching infinity, they would create a black hole.

I don't understand what you will tell by this. Only two different atoms can form theoretically infinite compounds.

An example I had given.

It is down to what is available at the time, Oxygen in this case and what is energetically favourable.

I am not a chemist but here is an example that could be useful in terms of Biochemistry that you can relate to.

Carbon monoxide poisoning can be fatal as available O2 binding sites on the Haemoglobin are taken up with CO instead.

This bond is a lot stronger than the bond with O2 (about 200 times)

In order to force the Haemoglobin to give up the CO you have to place the patient in a hyperbaric Oxygen chamber.

In chemistry terms you are changing the O2 concentration and pressure.

This swings the equilibrium from CO-Hb to O2- Hb. Same molecules different reaction because of the different conditions.

I don't know why you telling this. It has nothing to do how many combinations we have if two kind of atoms will connect each other.
