A step-by-step explanation of how to draw the BeF2 Lewis Structure (Beryllium Fluoride).For the BeF2 Lewis structure we first count the valence electrons for the BeF2 molecule using the periodic table. Once we know how many valence electrons there are in BeF2 we can distribute them around the central atom and attempt to fill the outer shells of each atom. When we are done adding valence electrons we check each atom to see if it has an octet (full outer shell). We also need to check to make sure we only used the number of available valence electrons we calculated earlier (no more, no less). The BeF2 Lewis structure has a total of 16 valence electrons.In the Lewis dot structure for BeF2 beryllium only needs four valence electrons (it`s an exception to the octet rule). If we`re not sure it`s the correct we can check the formal charges to make sure that our Lewis structure for BeF2 is correct.Note that there are a total of 16 valence electrons for the BeF2 Lewis structure.Get more chemistry help at
