Why does valency of nitrogen change while reacting with oxygen?
Wiki User
∙ 11y ago
Nitrogen can form a variety of compounds with oxygen, in which nitrogen has different valences, because reactions do not always go to completion, and oxidation does not always go to a state of maximum oxidation; the concentration of the reactants, the temperature at which the reaction takes place, and other variables affect the result.

How is the valency of oxygen two?
Since valency of oxide is 2 which is formed when electrons are gained by oxygen , hence valency of oxygen is also 2
Is a silver teapot turning black a chemical or physical change?
It is a chemical change but it can be reversed since that cahnge is only on the surface. It is merely an oxidization that occurs when silver is exposed to oxygen and has no contact with oil (which blocks the pores of the metal from reacting with oxygen).
Is rust a result of sulfur reacting with iron?
No. Rust forms from iron reacting with oxygen.
What are the components of clean air?
Argon, Carbon Dioxide, Nitrogen, oxygen, hydrogen
What is lighter oxygen or nitrogen?
Nitrogen is lighter than oxygen
What is the valency of oxygen?
Oxygen has 2 as its valency.

What is necessary for nitrogen to combine with oxygen?
They reacting together to form nitrogen oxides. N2o is a example.
Does oxygen exihibit variable valency?
it does. for example in H2O oxygen has a valency 2 while in hydrogen peroxide H2O2 oxygen exhibits valency 1
Can bacteria change nitrogen into oxygen?
No. Only a nuclear reaction can change oxygen into nitrogen, and bacteria are not capable of such reactions.
How do you find covalence of nitrogen in dinitrogen pentoxide?
according to old concept of valency ,valency of an element= 2xno. of oxygen atoms.here 1atom of N combines with 5/2 atom of O.thus covalency of N is 5
What is the valency and electronic configuration of oxygen?
Electron configuration for oxygen (O) is 1s2 2s2 2p4. The valency is 2-.
Is rusting of an iron hammer a chemical change and why?
yes because oxygen is reacting with iron
What is valency electrons of oxygen?
6
If the valency of Mn is 2 then how does it react with oxygen to form MnO2?
The valency of mn is also 4
What is the valence atoms of oxygen?
Oxygen has the valency of 2 in most of the compounds.
