# Write a single lewis structure for so2 in which all atoms

For a neutral molecule this is nothing more than the sum of the valence electrons on each atom. Thus, the ClO3- ion has a total of 26 valence electrons.

Every once in a while, we encounter a molecule for which it is impossible to write a satisfactory Lewis structure. Because neither boron nor fluorine falls in this category, we have to stop with what appears to be an unsatisfactory Lewis structure. This leaves six nonbonding electrons.

Carbon has four valence electrons, and oxygen has six. The valence electrons are therefore divided into two categories: When that happens, we expand the valence shell of the central atom. It is also useful to recognize that the formulas for complex molecules are often written in a way that hints at the skeleton structure of the molecule.

This is enough, however, to satisfy the octets of the carbon and oxygen atoms. This raises an interesting question: How does the sulfur atom in SF4 hold 10 electrons in its valence shell?

If the molecule carries an electric charge, we add one electron for each negative charge or subtract an electron for each positive charge. Use two valence electrons to form each bond in the skeleton structure.

As a result, we run out of electrons while the boron atom has only six valence electrons. Because the 3d orbitals on a neutral sulfur atom are all empty, one of these orbitals can be used to hold the extra pair of electrons on the sulfur atom in SF4.

The result is a Lewis structure in which each atom has an octet of valence electrons. Because there are four of these atoms, so we need 24 nonbonding electrons for this purpose.

We have already satisfied the octets for all five atoms, and we still have one more pair of valence electrons. Consider boron trifluoride BF3 which contains 24 valence electrons. Consider formaldehyde H2CO which contains 12 valence electrons. Because it takes two electrons to form a covalent bond, we can calculate the number of nonbonding electrons in the molecule by subtracting two electrons from the total number of valence electrons for each bond in the skeleton structure.

The electron configuration for a neutral sulfur atom seems to suggest that it takes eight electrons to fill the 3s and 3p orbitals in the valence shell of this atom.Write a single Lewis structure that obeys the octet rulefor and assignthe formal charges on all the atoms.
