Lewis structure
Draw the Lewis structure of chlorine pentafluoride. Start by drawing the overall structure of the molecule: Count the total valence electrons of the chlorine (n_Cl, val = 7) and fluorine (n_F, val = 7) atoms: n_Cl, val + 5 n_F, val = 42 Calculate the number of electrons needed to completely fill the valence shells for chlorine (n_Cl, full = 8) and fluorine (n_F, full = 8): n_Cl, full + 5 n_F, full = 48 Subtracting these two numbers shows that 48 - 42 = 6 bonding electrons are needed, which are already accounted for in the structure. Note that the valence shell of chlorine has been expanded to 5 bonds. After accounting for the expanded valence, there are 5 bonds and hence 10 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 42 - 10 = 32 electrons left to draw: Answer: | |
