The first step in this process involves calculating the number of valence electrons in the molecule or ion. 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.
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.
This leaves one pair of nonbonding electrons, which can be used to fill the octet of the central atom. For all but the simplest molecules, the following step-by-step process is faster. Consider boron trifluoride BF3 which contains 24 valence electrons.
When that happens, we expand the valence shell of the central atom. We start by writing symbols that contain the correct number of valence electrons for the atoms in the molecule.
There are three covalent bonds in the most reasonable skeleton structure for the chlorate ion. Thus, all of the nonbonding electrons are consumed by the three fluorine atoms.
As a result, six of the 26 valence electrons must be used as bonding electrons. We have already satisfied the octets for all five atoms, and we still have one more pair of valence electrons.
Use two valence electrons to form each bond in the skeleton structure. But there are 26 nonbonding electrons in this molecule. The formula of acetic acid is often written as CH3CO2H, because this molecule contains the following skeleton structure.
Consider formaldehyde H2CO which contains 12 valence electrons. Because there are four of these atoms, so we need 24 nonbonding electrons for this purpose. 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.
Every once in a while, we encounter a molecule for which it is impossible to write a satisfactory Lewis structure.The trial structure is You have 20 valence electrons in your trial structure.
The valence electrons you have available are: "1 Cl + 2 O + 1 e" = 1×7 + 2×6 + 1 = Hence, the trial structure has the correct number of electrons.
