A step-by-step explanation of how to draw the SeBr4 Lewis Dot Structure. • For the SeBr4 structure use the periodic table to find the total number of valence electrons for the SeBr4 molecule. Once we know how many valence electrons there are in SeBr4 we can distribute them around the central atom with the goal of filling the outer shells of each atom. • In the Lewis structure of SeBr4 structure there are a total of 34 valence electrons. SeBr4 is also called Selenium tetrabromide. • Note that SeBr4 can have an Expanded Octet and have more than eight valence electrons. Because of this there may be several possible Lewis Structures. To arrive at the most favorable Lewis Structure we need to consider formal charges.
