is there some rule that states the formal charge on the central atom should be zero? like if you have to have atoms within a molecule with a +1 and -1 to make the overall charge 0, is there a rule that states the central atom should have a formal charge of 0 and the other atoms should be the ones with the charges?
There is no particular rule, but since your central atom is typically the least electronegative one, it is the least likely to have a charge on it since the surrounding atoms are more likely to take the electrons.

If the central atom happens to be anything below or above 0, then it will affect the overall charge of the molecule.
