### Central Atom FC

In general, how do we determine which atom gets the FC of 0??? I know that we want all if not most atoms to have a FC of 0, but in the case for anions it is different. For example, if we have a central atom and a bonding atom and one of them can be 1- and the other can be 0 (in regards to FC), which one should we keep as 0 and which one should be 1-???

The atom that is more electronegative will tend to have the FC of -1, which in most cases is the bonding atom.
