One good pattern to remember is that resonance structures involve a π bond, one way or the other. It is either making a bond or breaking a bond or both. Therefore, whenever asked to draw a resonance structure(s), look for a π bond. You can’t have resonance structures with having a π bond involved. Because the side is not important, the Lewis electron dot diagram could also be drawn as follows: The electron dot diagram for helium, with two valence electrons, is as follows: By putting the two electrons together on the same side, we emphasize the fact that these two electrons are both in the 1 s subshell; this is the common convention we ...

When two atoms are joined by a covalent bond, the bond will have polar character when the electronegativities of the two atoms are different. The geometry of PO(OH)3 is tetrahedral with an unsymmetric charge distribution. Therefore this molecule is polar.Lewis structures can be utilized to make predictions about the layout of a molecule. Though a Lewis structure may seem intimidating at first glance, it is actually fairly easy to understand a Lewis structure and to draw one yourself, if you break down the creation of the Lewis structure into simple steps. If we look at this sulfur right here and we count our electrons, we have two, four, six, and then two more for a total of eight. So we have an octet of electrons around sulfur. So for this resonance structure, we have an octet of electrons, but we have formal charges. Down here we have an expanded valence shell, but we have zero formal charges.
