Problem: Determine the formal charge of each element in the following:(a) O22−(b) H2O2

FREE Expert Solution

We’re being asked to determine the formal charge of ALL ELEMENTS in O22- and H2O2.


To do so, we need to do the following steps:


Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Calculate the formal charge for the indicated atom. 


Recall that the formula for the formal charge is:


F.C.=Group No. -Bonds+Nonbonding electrons
