What is the formal charge on the sulfur atom in so? use the periodic table as needed. express the formal charge numerically

Both the S and O belong to group 6A elements, thus, both possess similar valence electrons, that is, six and equivalent sharing of bonding electrons. The formal charge is determined by using the formula, formal charge = valence electrons - (nonbonding electrons + bonding electrons)

The formal charge on the sulfur atom in SO is:  

Formal charge on S atom = 6 - (4 + 2) = 0

Hence, the formal charge on the S atom is 0.  

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
