Lewis structure
![Draw the Lewis structure of methylamine. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4), hydrogen (n_H, val = 1), and nitrogen (n_N, val = 5) atoms: n_C, val + 5 n_H, val + n_N, val = 14 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), and nitrogen (n_N, full = 8): n_C, full + 5 n_H, full + n_N, full = 26 Subtracting these two numbers shows that 26 - 14 = 12 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 6 bonds and hence 12 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 14 - 12 = 2 electrons left to draw: Answer: | |](../image_source/d58ebb6ab6e8623fb9851050ce7a5d9e.png)
