If nitrogen has a positive valence, how could it form with carbon, if negative how could it form with oxygen?

Question

Here nitrogen presents symbolically as positive valence in nitrate molecule.
http://en.wikipedia.org/wiki/Nitrate


Here hydrogen cyanide HCN needs a negative valence to form with postive valent carbon and hydrogen, but as seen above, nitrogen is postively valent.
http://en.wikipedia.org/wiki/Cyanide

So I guess the real question is, is an electron forced into the molecule at chemical joining reaction in HCN formation, or is an electron ejected for nitrate formation. I can not seem to mathematically resolve for the insufficiency of electron/protron differential needed for electro atomic attraction.

We know that that electro bonding of atoms forming molecules needs an electron differential and that 'transfer' is not an adequate description of how the electron differential forms the mechanics for the atom to atom bond for molecule formation. In these simple molecules neither the numbers eight nor sixteen nor thirtytwo are realistic quantifications for their formations as in HCN, the hydrogen is positive with one ineffctual electron opposed to its positive proton force, the proton exerting an unknown quantity of electron force units and the one carbon is positive with an unknown electron power unit differential and that is less than the proton force for that atom. So which gains the electron and when. I assume it is the nitrogen atom. What number of electron units and from where do these electrons come and how, I assume the source is their undifferentiated envirnoment with free electrons.

But with nitrates nitrogen is one electron less than neutrality?

I am not a'chem student'

I can't imagine a condition in which oxygen could continue any other valence than negative for an extended duration of time as it is so ready to combust with the combustable. Does heat draw electrons? That would contradict electro thermo resistance theory.

Helmut has explained the math to a satisfying degree. Nitrogen could oppose its its own valence by -5 and +5, an equal ratio for valence potential of positive and negative. These ratios work even though they do express precise and accurate electron force units. Tips hat to Helmut. Thanks.

" Nitrogen has 2 valences, -3 and +5. HCN is not a good example, as it can be postulated using either valence:
H(+1)C(+4)N(-5) or H(-1)C(+4)N(-3). The nitrate ion can be explained by N(+5)O(-2)3 Nitrogen just don't seem to wanna play by the rules (N2, NO, NO2). "

So, in other words, nitrogen has a bipolar valencability. If +5 and -5, then it consistently functs.

H(+1)C(+4)N(-5)[hydrogen is positive] or H(-1)C(+4)N(-3)[hydrogen is negative]. H two O [water] hydrogen is positive, postive enough to hold two oxygen atoms very rigidly withstanding very high temperatures.

'HCN is not a good example, as it can be postulated using either valence: H(+1)C(+4)N(-5) or H(-1)C(+4)N(-3). ' Actually the valences are the same polarity in those two examples, but there is a ratio difference of two. The ratio of polarities in the first chemical descriptor is equal, sum of ratio numerical values positive equals 5, sum of ratio numerical values negative in the nitrogen atom 5, compare to -4,+4.

Hifliers: ' nitrogen due to its half filled electronic configuration it is able to form both type of ions. '

The word 'half' may be very apt for a good theory here; an equal bipolar valence potential of an atom would explain the wide range nitrogen presents as a molecular constituent. Molecules that are formed or destroied at the biothermo temperatures need valence instability (unequal ratio of polarity in the molecule) for that mean of temperature that serves as needed condition for the maintainance for living things. For example the nitrators or nitraters that fabricate nitrates in the soil at the roots of plants or the utilization of surgars in the blood and DNA.

Perhaps I should leave this question open for a time longer.

JD:" well u know that sometimes non metals bond "covalently" meaning that they dont lose or gain their electrons but they simply share with each other........ "

No, I didn't know that. What kind of energy transaction is there in their reaction with each other if not electromagnetic or heat. Please provide data sources.

"pls note that atoms (eg, oxygen, nitrogen) have no charge its when they bond with metals that they get it. When they bond with their likes ( non metals) they dont have a charge becuz of sharing

So, in other words, in their molecules ,non-metal constituent molecules, their combined proton force is equal to their electron force? Would that not make them an inert (unreactive with everything) class of molecule? What about salt NaCl? How does it melt ice.

"NB: covalent componds have no charge "

NB?

Perhaps this is why they call nitrogen a noble gas, because it is accepting of both electromagnetic polarities.

But if nitrogen can do thatm why not C and O?

Jane: " It depends on whether oxygen is positive, negative, or neutral. An electron of one atom is transfered or shared with another atom, so that the second atom has a valence electron count of eight, sixteen, or thirty two."

Thanks Jane, Yes, as Helmut has co-oberated atoms can have a changing valent signature. Could you give a link for your electron count 'second atom has a valence electron count of eight, sixteen, or thirty two." It does follow that an amount of protons would hold a ranger of possible electrons, but then their are neutrons to consider, and the mass of each sub-atomic particle class is unequal as is their electro-force potentials. e.g. a proton could have an absolute force value of 2 electrons or 100, and a neutron? It could have a third polarity for all I know in an unknown about of absolute force values in electron force units.

If elementary atomic mass differentials are stable, constant in time in their relative differences, then their force ratios too.

The electron in the quantum mechanics of atomic to molecular joining/splitting (chemical reaction): enjoined in a harmony of repetitive action/interaction of free electrons in a molecular structure, the distance of electron from atomic neucleus, the mass difference of atomic neucleus and electron number gives a fractional electron force which may be surplus or deficit of negative force, the proton providing a constant presence of positive force in the neucleus for the atom. This imbalance for the negative electron force gives variance for reaction to other atoms/elements, allowing the release or inclusion for an electron or more at a fraction of a whole electron force. The atomic and/or molecular structure, having a surplus or deficit of negative force, is ready for other constituent inclusion with other atoms and/or molecules. The fraction of electron force, with the mass and distribution of mass through space, determines the needed energy change for constituent joining/splitting.yes?

" But if it is combined with hydrogen, it will be negative."

Answer 1

It depends on whether oxygen is positive, negative, or neutral. An electron of one atom is transfered or shared with another atom, so that the second atom has a valence electron count of eight, sixteen, or thirty two.

Answer 2

Nitrogen has 2 valences, -3 and +5. HCN is not a good example, as it can be postulated using either valence:
H(+1)C(+4)N(-5) or H(-1)C(+4)N(-3). The nitrate ion can be explained by N(+5)O(-2)3 Nitrogen just don't seem to wanna play by the rules (N2, NO, NO2).

Answer 3

Have you studied electronegativity, or oxidation states? Whether N is formally positive or negative in its covalent compounds and ions depends on what it has combined with. If the other element is oxygen (more electronegative) then N will have a theoretical positive charge called an oxidation state. But if it is combined with hydrogen, it will be negative. This will influence whether that particular nitrogen-containing species is an oxidising agent or a reducing agent.

Answer 5

nitrogen due to its half filled electronic configuration it is able to form both type of ions.
