Lewis structure
![Draw the Lewis structure of hydrogen chloride. Start by drawing the overall structure of the molecule: Count the total valence electrons of the chlorine (n_Cl, val = 7) and hydrogen (n_H, val = 1) atoms: n_Cl, val + n_H, val = 8 Calculate the number of electrons needed to completely fill the valence shells for chlorine (n_Cl, full = 8) and hydrogen (n_H, full = 2): n_Cl, full + n_H, full = 10 Subtracting these two numbers shows that 10 - 8 = 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 8 - 2 = 6 electrons left to draw: Answer: | |](../image_source/911dd6c758fd08fc22d5917c690f8942.png)
