In ionic bond formation, the lattice energy of ions _____ as the magnitude of the ion charges _____ and the radii _____. increases, increase, decrease For the questions that follow, consider the BEST Lewis structures of the following oxyanions: EXERCISES - BASIC CONCEPTS OF CHEMICAL BONDING - 8.52 For each of the following molecules or ions of sulfur and oxygen, write a single Lewis structure that obeys the octet rule, and calculate the oxidation numbers and formal charges on all the atoms:(a) SO 2, (b) SO 3, . (d) Arrange these molecules/ions in order of increasing SO bond distance. _____ Formal Charges and Resonance ChemistryAll oxygen atoms, however, are equivalent, and the double bond could form from any one of the three atoms. This gives rise to three resonance forms of the carbonate ion. Because we can write three identical resonance structures, we know that the actual arrangement of electrons in the carbonate ion is the average of the three structures.
