Difference between FC & Ox # is in the determination of “possession #”. FC: divide the bonding electrons up between bonded atoms ( i.e., consider the bonding to be purely covalent. ) Ox #: the more electronegative atom gets both of the bonding electrons ( i.e ., consider the bonding to be purely ionic. ) Section 5.8 Lewis Structure: Sulfite Ion SO 3 2- S O O O ER = 4*8 = 32 e-s VE = 6 + 6 +6 +6 +2 = 26 e-s 6 e-s / 2 = 3 bonds Section 5.8 20 e-s / 2 = 10 lone pairs FC: divide the bonding electrons up between bonded atoms.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
