Formal charge of an atom is the charge assigned to it in a molecule. FC = V - (N + B \2) Where V is the number of valence electrons of the atom in isolation (atom in ground state); N is the number of non-bonding valence electrons on this atom in the molecule; and B is the total number of electrons shared in covalent bonds with other atoms in the molecule. There are two electrons shared per single covalent bond.

What is the formal charge for BrO2?
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.
What is the formal charge of H in HCO3-?
If youre looking for the formal charge of the Molecule HCO2- then its just the -1. If youre looking for individual Atom formal charges, dram the lewis diagram of the entire atom. Draw out all of the single or double bonds and add all the lone electrons. USe the equation (Group number of element-lone electrons-Bonding electrons/2) This will be your formal charge for each atom.

How do you find how many electrons an atom has?
Knowing which element it is and its formal charge, subtract the charge from its atomic number.
What formal charge does carbon have?
The formal charge on the carbon atom of carbon monoxide in its major resonance form (triple bonded with oxygen) is -1. However, the electronegativity difference cancels it out for the most part (oxygen in this case as a formal charge of +1). It would be more accurate to say that there is simply a small dipole moment between the two molecules with the negative end on carbon.
How is the shape of the molecules of polyatomic ions related to the number of electron pairs surrounding the central atom?
Because, if the atom is being created there will such time that it will destroy, n. There are no lone pairs of electrons left. Thus, using the definition of formal charge, hydrogen has a formal charge of zero (1- (0 + ½ × 2)) and nitrogen has a formal charge of +1 (5− (0 + ½ × 8)). After adding up all the formal charges throughout the molecule the result is a total formal charge of +1, consistent with the charge of the molecule given in the first place.

What is the Difference between valency and oxidation state?
Valency is the number of electrons in the valence shell. Oxidation state is the formal charge on an atom/ion.
