Chemistry 1110 Covalent Structures I. For each element, tell the number of valence electrons it holds and give the electron dot symbol for the neutral element. If this element were to form an ion, what kind of ion would it form. C Br Ne O F S P Si Cl Se H I B N He II. Draw the appropriate Lewis structures for the following compounds (First, draw the electron-dot symbols for each element, then put them together in such a way that gives each a full shell): Cl2 Br2 H2O NH3 H2S CH4 OF2 CCl4 III. Draw the appropriate Lewis structures for the following compounds & polyatomic ions NF3 CO2 CH2O SiCl4 C2H6 C2H4 C2H2 HCN NH4+ CO32- NO2- NO2+V. For each of the following molecules, draw the Lewis dot structure, give the number of electron sets and determine both the electronic and the molecular geometry surrounding the central atom. Then redraw the molecule in its proper geometric shape. SO3 CBr4 H2Se NH3 SiO2 CCl2O N2O BH4- NOF HCN HOCl SOCl2 SO2 SO32-
