Question

find the oxidation number of NH4​

Answer 1

Answer:

NH4 has +1 charge the oxidation state or number of nitrogen is -3 and hydrogen has +1.

So the overall change is +1.

Answer 2

The oxidation number of NH4​ is -3

Explanation:

1. As the sum of the individual oxidation numbers is equal to the charge on the ion, the sum is -3

2. We have the ammonium ion, NH+4 As you can see from the formula, it has a +1 charge.

3. Since nitrogen is more electronegative than hydrogen, hydrogen will occupy a +1 charge. There are four hydrogen atoms in this ion, so the total charge of the hydrogens is +1⋅4=+4
