Chem101 S18 W... 5. Lattice energy is the change i energy that is associated with forming a crystal line lattice of a compound from the gasenus ions. e.g. Na (B) + Cl.(s) ? NaCl(s}. A large negative value of lattice energy means that a lot nf eergy will be given off when the ions coe together to farnm the lattice. Choose the correct option in the statements below a. More energy will be given off when ons have a LARGER/SMALLER charge. b. More energy ll be given off when ions in the lattice are FURTHER APART! CLOSER TOGETHER c lons w h closer together in the lattice when theii radii ae LARGER SMALLER 6. For which compound (LUF, MES, BaS, RbFI would you expect... the highest(more negative) Lattice Energy? a. b. The highest melting point leergy tn disrupt the latticel? 7. Recall that Z."-# protons-core electrons, and that the nucleus on valence electrons. Circle the correct option for both of the following statements about electronegativity higher Zei results in stronger "pull" of a. Electronegativity should increase as sl INCREASES/DECREASES Electronegativity should increase as dlistance of the alence electron from the nucleus INCREASES/DECREASES b. 8. dentify the elements basedl on their electron configuration and rank them in order of electronegativity The eleient symbol is The element symbol is__ The element symbol is_ The element symbol is_ Least electronegative Most electronegative
