* Hydrogen (H) typically has an oxidation state of +1.

* Ammonia (NH₃) is a neutral molecule, meaning the sum of the oxidation states of all atoms must equal zero.

Let "x" represent the oxidation state of Nitrogen (N).

* We have 3 hydrogen atoms with +1 oxidation state each: 3 * (+1) = +3

* The oxidation state of nitrogen (x) plus the oxidation state of hydrogen (+3) must equal zero: x + 3 = 0

Solving for x, we get:

* x = -3

Therefore, the oxidation state of N in NH₃ is -3.
