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.
The chemical name for BrO2 is bromine dioxide. Be careful though - bromite, which is different, is the name for the chemical BrO2-.
The formula for magnesium bromite is Mg(BrO2)2.
Bromite is BrO2- (from the acid HBrO) so its charge is -1, minus one.
The chemical name for BrO2 is bromine dioxide. Be careful though - bromite, which is different, is the name for the chemical BrO2-.
The formal charge of the NCO molecule is zero.

The formal charge of the NCO molecule is zero.
The formal charge of the SO42- ion is -2.
The formal charge of the CH2N2 molecule is zero.

The formal charge of nitrite (NO2-) is -1. Each oxygen atom carries a formal charge of -1, while the nitrogen atom carries a formal charge of +1, leading to an overall charge of -1 for the nitrite ion.
Such an ion would most likely carry a 1+ charge.
The formal charge of ICl3 is 0. Each iodine atom has a formal charge of 0, while each chlorine atom has a formal charge of -1, adding up to a total of 0 for the entire molecule.
The most optimal Lewis structure for the cyanate ion, NCO-, based on formal charge, is where the nitrogen atom has a formal charge of 1, the carbon atom has a formal charge of 0, and the oxygen atom has a formal charge of -1.
