How would you draw the Lewis structure of BeCl2?

The BeCl2 Lewis structure is similar to BeF2 since F is in Group 7 and has 7 valence electrons. Beryllium (Be) doesn't need 8 valence electrons to have an octet (Be often only needs 4). If you're not sure you have the best Lewis structure for BeCl2 you can calculate the formal charges. You'll find the Be in BeCl2 only has 4 valence electrons. For the BeCl2 Lewis structure there are a total of 16 valence electrons available.
