**N2h4 Oxidation Number**

What is the oxidation number of N in N2H4? 3

The oxidation number of N is +2.

Hydrogen, when bonded to a non-metal, has an oxidation number 1.

Since there are 4 hydrogen atoms, the total hydrogen is SS4.

The oxidation number of a compound is 0.

Therefore, the global value of the OS is N + 4.

Since 2 N are atoms, the S.O of N is +2.

H = +1 and N = 2
