Lewis structure
Draw the Lewis structure of tellurium hexafluoride. Start by drawing the overall structure of the molecule: Count the total valence electrons of the fluorine (n_F, val = 7) and tellurium (n_Te, val = 6) atoms: 6 n_F, val + n_Te, val = 48 Calculate the number of electrons needed to completely fill the valence shells for fluorine (n_F, full = 8) and tellurium (n_Te, full = 8): 6 n_F, full + n_Te, full = 56 Subtracting these two numbers shows that 56 - 48 = 8 bonding electrons are needed, which are already accounted for in the structure. Note that the valence shell of tellurium has been expanded to 6 bonds. After accounting for the expanded valence, 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 48 - 12 = 36 electrons left to draw: Answer: | |
