The oxidation number of nitrogen in most compounds is -1
***************2nd Opinion *******************
I don't think so. Nitrogen has many oxidation numbers. +5 is pretty common, as found in nitrates. +3 is found in nitrites. -3 is found in ammonia and nitrides. What is the most common? That I don't know.
+1 is the most common. The only exceptions I can think of are in hydride's such as LiH, peroxides such as H2O2 and super oxides such as HO2, in all of these cases it is -1.
The oxidation number of an oxide ion in most compounds is -2.
It varies on the compound of nitrogen. -3 in nitrides is the most common. But oxidation number up to +5 is possible.
Nitrogen has an oxidation number of -3. Since it is in group 15, it has 5 valence electrons. It wants to have eight, so it will gain three electrons. Electrons are negative, that's why the oxidation number is negative.
Chlorine, bromine, and iodine can have both 1+ and 1- oxidation states. They most often occur in the 1- oxidation state, often in tho form , especially as the ions Cl-, Br-, and I- but can also achieve as 1+ oxidation state, particularly in the oxyanions ClO-, BrO-, IO- and the corresponding acids.
Hydrogen has an oxidation number of +1 in most of its compounds and -1 in metal hydrides and hydrocarbons.
0 in the elemental form, +2 and +3 (most common) in its compounds. But osmium can form compounds with oxidation number up to +8 (maximum)
The oxidation number of oxygen is -2 in most of its compounds
