Lewis structure
![Draw the Lewis structure of aluminum tribromide. Start by drawing the overall structure of the molecule: Count the total valence electrons of the aluminum (n_Al, val = 3) and bromine (n_Br, val = 7) atoms: n_Al, val + 3 n_Br, val = 24 Calculate the number of electrons needed to completely fill the valence shells for aluminum (n_Al, full = 6) and bromine (n_Br, full = 8): n_Al, full + 3 n_Br, full = 30 Subtracting these two numbers shows that 30 - 24 = 6 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 3 bonds and hence 6 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 24 - 6 = 18 electrons left to draw: Answer: | |](../image_source/957bfa83a5f0f584ebcdcfdc18b11439.png)
