Draw the Lewis structure of aluminum nitride. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the aluminum (n_Al, val = 3) and nitrogen (n_N, val = 5) atoms: n_Al, val + n_N, val = 8 Calculate the number of electrons needed to completely fill the valence shells for aluminum (n_Al, full = 6) and nitrogen (n_N, full = 8): n_Al, full + n_N, full = 14 Subtracting these two numbers shows that 14 - 8 = 6 bonding electrons are needed. Each bond has two electrons, so in addition to the 1 bond already present in the diagram add 2 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 2 bonds by pairing electrons between adjacent highlighted atoms: Answer: | |
