Lewis structure
Draw the Lewis structure of iodine bromide. Start by drawing the overall structure of the molecule: Count the total valence electrons of the bromine (n_Br, val = 7) and iodine (n_I, val = 7) atoms: n_Br, val + n_I, val = 14 Calculate the number of electrons needed to completely fill the valence shells for bromine (n_Br, full = 8) and iodine (n_I, full = 8): n_Br, full + n_I, full = 16 Subtracting these two numbers shows that 16 - 14 = 2 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There is 1 bond and hence 2 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 14 - 2 = 12 electrons left to draw: Answer: | |
