Lewis structure
Draw the Lewis structure of ammonia-15 N. Start by drawing the overall structure of the molecule: Count the total valence electrons of the hydrogen (n_H, val = 1) and nitrogen (n_N, val = 5) atoms: 3 n_H, val + n_N, val = 8 Calculate the number of electrons needed to completely fill the valence shells for hydrogen (n_H, full = 2) and nitrogen (n_N, full = 8): 3 n_H, full + n_N, full = 14 Subtracting these two numbers shows that 14 - 8 = 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 8 - 6 = 2 electrons left to draw: Answer: | |
