Lewis structure
![Draw the Lewis structure of chlorine trifluoride. 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 + 3 n_F, val = 28 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 + 3 n_F, full = 32 Subtracting these two numbers shows that 32 - 28 = 4 bonding electrons are needed, which are already accounted for in the structure. Note that the valence shell of chlorine has been expanded. After accounting for the expanded valence, 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 28 - 6 = 22 electrons left to draw: Answer: | |](../image_source/17c6d46b2a2f8eca3c7852d941422add.png)
