Why there arise negative oxidation state for N?
Description: Why there arise negative oxidation state for N? Because of the difference in the EN between H2.1 N3.0. Example :-NH3 (N -III), N2H4 (-II), NH2OH(-I) ,N2 (0), N2O (I), NO (II), HNO2(III), NO2(IV) HNO3(V). Nitrogen The (VB) Group

slide2. Why there arise negative oxidation state for N?
Because of the difference in the EN between H=2.1 & N=3.0.
Example :-NH3 (N -III), N2H4 (-II), NH2OH(-I) ,N2 (0), N2O (+I), NO (+II), HNO2(+III), NO2(+IV) & HNO3(+V). Nitrogen & The (VB) Group Element The electronic structure & the oxidation state<br>
slide3. Nitrogen can fill the outer shell to be 8es by:
1.Gains 3es forming N3- (Nitrides of alkaloids elements)
2.Forming single covalent. Bonds (e.g.NH3) or multiple (e.g. N≡N).
3.Forming covalent. bonds with loosing e, e.g. [NH4]+.
4.Forming covalent. bonds with gaining e, e.g. NH2- amide.
There will be stable nitrogen compounds, the outer shell of nitrogen is incomplete (e.g.NO or NO2) each N contains one unpaired e. They have paramagnetic properties.
Nitrogen forms multiple bonds differing from the other gr. elements, so it likes C & O. The bond (N-N) is weaker than that in (C-C) because of the repulsion of the non –bonding electrons on the Nitrogen atoms.<br>
