How can compounds be shown with electron dot diagrams?
Elements that do not have complete sets of valence electrons tend to react. In certain cases, the reaction involves the transfer of electrons between atoms. You can describe this process by using electron dot diagrams. Use the animation tools in presentation software to illustrate the formation of two different ionic compounds. Each animation should show how the transfer of one or more electrons between atoms results in the formation of the compound.
