    A. The element phosphorous just has an atomic symbol of P. The prefix penta tells you that there are 5 Chlorine atoms. So molecule is...\[PCl_5\]B. The atomic symbol for Iodine is just I. Hepta means 7, so there are 7 fluorine. In this molecule, all 7 of iodine's valence electrons are being shared. \[IF_7\]C. -Tri means 3, so there are 3 fluorine. \[ClF_3\]D. -Di means 2. Iodine dioxide is just like carbon dioxide, CO2. \[IO_2\]

    Well, Google shows that it's correct. It's usually written as...\[OIO\]But that's beside the point.
