List each of the steps in thecycle and show how the cycle is used to calculate lattice energy.12.How does lattice energy relate to ionic radii? To ion charge?13.How does the ionic bonding model explain the relatively highmelting points of ionic compounds?14.How does the ionic bonding model explain the nonconductivityof ionic solids, and at the same time the conductivity of ionicsolutions?15.Within a covalent Lewis structure, what is the difference be-tween lone pair and bonding pair electrons?16.In what ways are double and triple covalent bonds differentfrom single covalent bonds?17.How does the Lewis model for covalent bonding account forwhy certain combinations of atoms are stable while othersare not?18.How does the Lewis model for covalent bonding account for therelatively low melting and boiling points of molecular com-pounds (compared to ionic compounds)?19.What is electronegativity? What are the periodic trends in elec-tronegativity?20.Explain the difference between a pure covalent bond, a polarcovalent bond, and an ionic bond.21.Explain what is meant by the percent ionic character of a bond.Do any bonds have 100% ionic character?Cl-?Na+22.What is a dipole moment?23.What is the magnitude of the dipole moment formed by separat-ing a proton and an electron by 100 pm? 200 pm?24.What is the basic procedure for writing a covalent Lewisstructure?25.How do you determine the number of electrons that go into theLewis structure of a molecule? A polyatomic ion?26.What are resonance structures? What is a resonance hybrid?27.Do resonance structures always contribute equally to the overallstructure of a molecule? Explain.28.What is formal charge? How is formal charge calculated? Howis it helpful?29.Why does the octet rule have exceptions? Give the three majorcategories of exceptions and an example of each.30.What elements can have expanded octets? What elementsshould never have expanded octets?31.What is bond energy? How can average bond energies be usedto calculate enthalpies of reaction?32.Explain the difference between endothermic reactions andexothermic reactions with respect to the bond energies of thebonds broken and formed.33.What is the electron sea model for bonding in metals?34.How does the electron sea model explain the conductivity ofmetals? The malleability and ductility of metals?TROMC09_358-397hr.qxd13-11-200914:58Page 394
