Draw the Lewis structure of selenium tetrafluoride. Start by drawing the overall structure of the molecule: Count the total valence electrons of the fluorine (n_F, val = 7) and selenium (n_Se, val = 6) atoms: 4 n_F, val + n_Se, val = 34 Calculate the number of electrons needed to completely fill the valence shells for fluorine (n_F, full = 8) and selenium (n_Se, full = 8): 4 n_F, full + n_Se, full = 40 Subtracting these two numbers shows that 40 - 34 = 6 bonding electrons are needed, which are already accounted for in the structure. Note that the valence shell of selenium has been expanded. After accounting for the expanded valence, there are 4 bonds and hence 8 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 34 - 8 = 26 electrons left to draw: Answer: | |
