Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

For each of the following, draw the Lewis dot structure, give the electron arrangement (E.A.) and the molecular geometry (M.G.):

 $$PF_5$$ $$CS_2$$ $$BrO_3^-$$ $$NH_4^+$$ $$SCl_4$$ $$BrF_5$$ $$BF_3$$ $$SCl_6$$ $$PH_3$$ $$NF_3$$ $$SO_4^{2-}$$ $$CO_3^{2-}$$ $$SiCl_4$$ $$ClO_3^-$$ $$CH_2O$$ $$NO_3^-$$ $$O_3$$ $$CCl_4$$ $$AlH_3$$ $$SO_2$$ $$SO_3$$ $$CO$$ $$CHCl_3$$ $$BrF_3$$ $$H_2S$$ $$I_3^-$$ $$H_3O^+$$
