A stable triatomic molecule can be formed that contains one atom each of nitrogen, sulfur, and fluorine. Three bonding structures are possible, depending on which is the central atom: NSF, SNF, and SFN.
(a) Write a Lewis diagram for each of these molecules, indicating the formal charge on each atom.
(b) Often, the structure with the least separation of formal charge is the most stable. Is this statement consistent with the observed structure for this molecule— namely, NSF, which has a central sulfur atom?
(c) Does consideration of the electronegativities of N, S, and F from Figure 3.18 help rationalize this observed structure? Explain. 100. The gas

for this molecular ion.
(b) Compute the formal charges on all atoms in the
molecular ion in each of the six Lewis diagrams.
(c) Determine the charge on each atom in the polyatomic

charge resident on each N atom is –0.375 and on
each S atom is +0.041. Show that this result is consis-
tent with the overall +1 charge on the molecular ion.
