Question

What is the oxidation number of nitrogen in NaNO2?

Answer 1

Answer:

the oxidation number of nitrogen would be 2 in NaNo2

Answer 2

Answer:

According to the calculation the oxidation number of nitrogen (N) in $Na NO_{2}$ is $+3$ .

Explanation:

Oxidation number:- The total number of electrons that an atom one or other of two gains or lose to form a chemical bond with another atom may be positive, negative, or zero. The sum of the oxidation number of all the atoms in the molecule equals zero.

Let's assume the oxidation number of nitrogen in $Na NO_{2}$ be $y$

$= 1+y+(-2)$×$2$

$y=+3$

Finally,

           by calculating the oxidation number of nitrogen in $Na NO_{2}$ is $+3$ .
