Formal Charge of Oxygen
why does oxygen usually have the negative formal charge in a lewis structure compared to carbon?

Re: Formal Charge of Oxygen
I had this question as well and from other students I have heard that the oxygen is more electronegative therefore it prefers to have the negative charge compared to Nitrogen if one of them has to have it.

Re: Formal Charge of Oxygen
The formal charge depends on the arrangement of electrons around the element. Maybe Oxygen was arranged in a way in which there were more lone pairs than shared pairs which caused it to have a negative formal charge.
Re: Formal Charge of Oxygen
In general, the more electronegative atom should have the negative formal charge since the electrons are more strongly attracted/pulled to them.

Re: Formal Charge of Oxygen
As the others said, the electronegativity of Carbon is lower than Oxygen, which causes oxygen to "hog" the electrons more, giving it a negative formal charge.

Re: Formal Charge of Oxygen
Oxygen is more electronegative than carbon which attracts the electrons to them usually giving it a negative charge.

Re: Formal Charge of Oxygen
Also keep in mind that formal charge only applies to compounds and not individual atoms.
