When you are finished, turn on Show electron dot diagram and check your answers. Show how Lewis dot diagrams also represent ionic bonding. The overlapping of the electron orbitals and the sharing of an electron pair is represented in part (a) of the following figure. Each hydrogen atom feels the effect of the two electrons each has, in a way, filled its valence energy level.
In the alternate Lewis dot diagram, there are two lines between each atom to show that two pairs of electrons are shared. The two electrons (one from each hydrogen atom) belong to both atoms. The remaining electrons are shown paired up around each oxygen atom. Use the Gizmo to create a neutral atom of each of the following elements. The Lewis dot diagram for carbon dioxide also shows that two pairs of electrons are shared. Lewis Structures are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Carbon dioxide. Practice: Turn off Show electron dot diagram.
