Question

If the oxidation number of nitrogen in a certain molecule changes from +3 to -2 during a reaction, is the nitrogen oxidized or reduced? how many electrons are gained or lost by the nitrogen atom?

Answer 1

the nitrogen has been reduced or has undergone reduction and it has gained one electron

Answer 2

Nitrogen has been reduced

What is Oxidation and Reduction ?

• Oxidation is defined as the process in which an atom or ion loses one or more electrons.

• Reduction is defined as the process in which an atom or ion gains one or more electrons.

Since here we can see that there is a negative -2 charge on nitrogen so there is gain of electron and hence it is reduced.
