A step-by-step explanation of how to draw the CaI2 Lewis Dot Structure.For CaI2 we have an ionic compound and we need to take that into account when we draw. A Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. Electrons exist outside of an atom‘s nucleus and are found in principal energy levels that contain only up to a specific number of electrons. Generating the Lewis dot Structure. To generate the Lewis dot structure, you have to follow the given steps: Find the total count of valence electrons to molecules. In this step, add the total count of valence electrons from all the atoms in a bit. Find the required count of electrons needed to make the atoms complete.
