How does a covalent bond difer from an ionic bond?
An ionic bond is due to attraction between positive and negative ions, while a covalent bond results from atoms sharing electrons. b) How do molecular compounds differ from ionic compounds. Molecular compounds have covalent bonds and often contain individual molecules. Ionic compounds have ionic bonds and contain ions bonded within a crystal lattice structure. 12. a) Draw Lewis dot diagrams for the following nonmetals: H, O, N, C b) What is the bonding capacity of valence of these four elements? H, O, N, C = 1, 2, 3, 4 respectively [covalent bonding occurs at the unpaired valence electron(s)] c) Draw Lewis structures for each of the following compounds: H2O, CO2, CH4, NH3, H2, N2, O2 Check your neighbor, or ask instructor to work some of these in class. 13. a) Draw Lewis structures for sodium chloride, water, and hydrochloric acid (HCl). b) Identify the bond type in each structure. c) Is the octet rule satisfied for each atom or ion? Check your neighbor, or ask instructor to work some
