There is this question in Chem 1A03 quiz that I am so lost about. Please help me.

Which of the following statements is/are true regarding the Lewis structures of SFO2- and SFO2+?

 1. There are four bonds about S in both species.
 2. There are more than eight electrons in the valence shell of one of the atoms in SFO2-.
 3. There are negative (-) formal charges in both species.
 4. There are positive (+) formal charges in both of these species.
 5. There are more than eight electrons in the valence shell of one of the atoms in SFO2+.


(2 in both cases is subscript).

On yahoo answers someone posted that the answer is 3 and 4. But I thought it was 2 and 5.

Thanks so much

I'm pretty sure you are right, the answer should be 2 and 5 from the formal charge minimized lewis structures.
