Lewis structure
Draw the Lewis structure of antimony(III) chloride. Start by drawing the overall structure of the molecule: Count the total valence electrons of the chlorine (n_Cl, val = 7) and antimony (n_Sb, val = 5) atoms: 3 n_Cl, val + n_Sb, val = 26 Calculate the number of electrons needed to completely fill the valence shells for chlorine (n_Cl, full = 8) and antimony (n_Sb, full = 8): 3 n_Cl, full + n_Sb, full = 32 Subtracting these two numbers shows that 32 - 26 = 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 26 - 6 = 20 electrons left to draw: Answer: | |
