There is a "zoo" full of nitrogen oxides! The most commonly encountered are NO, nitric oxide, an important biological molecule; N2O nitrous oxide (laughing gas); NO2 nitrogen dioxide, an intermediate in the production of nitric acid.
NO2
Nitrogen is in the 3- oxidation state in calcium nitride.
NO2 is a acidic gas. Nitrogen shows +4 oxidation number.
It depends on the compound. Nitrogen has compounds in which the oxidation numbers range from -3 to +5.
+4 for nitrogen
+5 oxidation state
+4 in nitrogen dioxide (NO2)
zero for each nitrogen
Nitrogen's oxidation number is -4.Carbon's oxidation number is +3.The cyanide ion has -1 charge. Nitrogen is in -3 state. By balancing the charges: the oxidation number of carbon is +4.
