it's -3. The oxidation number for hydrogen is +1. Since NH3 is not ionic compound, the total oxidation number should be 0. Ammonia has 3 hydrogen atoms, which gives the ox. number +3, the oxidation number of nitrogen should be +3 to make the total oxidation number equals to 0

Ammonium is NH4+
Ammonia gas is NH3
the oxidation number of N is -3, in each case
In cleaning solutions, NH3 dissolves readily and forms NH4OH

Each H is +1 and as NH3 is neutral N must be -3

as oxidation number of hydrogen in most of its compound is +1,
and the algebraic sum of oxidation numbers of all elements in a compound is 0,
so N should have O.N. -3
