What is the formal charge for BrO2?

Answer 1

The formal charge on bromine in the molecule HBr is -1.

There are a number of rules for assigning the formal charge to an atom. The most important of them is that the sum of the formal charges on each atom must equal the charge on the molecule or ion. Since the Br has a formal of -1 and the charge on HBr is zero, then the formal charge on the hydrogen atom must be +1. The bromine atom has a formal charge of -1 because another important rule is that the most electronegative atom will have a negative formal charge equal to the number of electrons it needs to fill all of its outer orbitals. Since bromine has seven electrons, it needs one electron to fill its outer shell.

Answer 2

The formal charge of BrO2 is 0. Each oxygen atom carries a charge of -1, while the bromine atom carries a charge of +1. The sum of the formal charges gives a total of 0, making the molecule neutral overall.
