The Charge of H2O2 is 0.
But the question is how can you say that the charge on H2O2 (Hydrogen peroxide) is 0?
Well you can say this by calculating its formal charge.
So let’s calculate the formal charge of H2O2 (Hydrogen peroxide).
If you are a visual learner like me, then here is a short two minute video for you.
Calculating the formal charge of H2O2 using lewis structure
In order to calculate the formal charge on H2O2 (Hydrogen peroxide), you should know the Lewis dot structure of H2O2.
Here is the lewis structure of H2O2 (Hydrogen peroxide).

Now using the above lewis structure of H2O2, you have to find the formal charge on each atom that is present in the H2O2 molecule.
For calculating the formal charge, you need to remember this formula;
Formal charge = Valence electrons – Nonbonding electrons – (Bonding electrons)/2
You can see the bonding and nonbonding electrons of H2O2 from the image given below.

So now let’s calculate the formal charge on each individual atom present in H2O2.
Formal charge on Hydrogen atom:
Valence electron = 1 (as it is in group 1 on periodic table) [1]
Nonbonding electrons = 0
Bonding electrons = 2
So according to the formula of formal charge, you will get;
Formal charge on Hydrogen = Valence electrons – Nonbonding electrons – (Bonding electrons)/2 = 1 – 0 – (2/2) = 0

So the formal charge on hydrogen atom is 0.
Formal charge on Oxygen atom:
Valence electron = 6 (as it is in group 16 on periodic table) [2]
Nonbonding electrons = 4
Bonding electrons = 4
So according to the formula of formal charge, you will get;
Formal charge on Oxygen = Valence electrons – Nonbonding electrons – (Bonding electrons)/2 = 6 – 4 – (4/2) = 0

So the formal charge on oxygen atom is 0.
Now you can see that all the atoms of H2O2 have 0 formal charge.
This indicates that the overall H2O2 (Hydrogen peroxide) molecule also has 0 charge and hence it is a neutral molecule.
I hope you have understood the above calculations for the formal charge of H2O2 (Hydrogen peroxide).
