[QUOTE="SherriB, post: 2184511, member: 770936"] 37.Which of the following best explains the periodic trend of atomic radius: a) the balance of positive and negative charges b) radius decreases from left to right and bottom too top c) the positive nuclear charge increases within a period without an increase energy level d) the opposites attract 38.Determine which of the following has the most polar bond: a) CCl4 b) SO3 c) NH3 d) F2 39.Indicate the charge on the metal ion in: FeCl2, CuO, Fe2S3, and AlP. 40.Write the correct formula, or name the following: Sodium nitrate copper (I) sulfate CaCO3 Cr2O3 Iron (III) carbonate 41.What elements on the periodic table are most likely to form covalent compounds? 42.How do covalent compounds differ from ionic compounds? 43.Which of the following list is now ionicallly bonded: a) KOH b) H2S c) CaO d) (NH4)2SO4 44.Which of the following is the most electronegitive: a) Cl b) K c) Ra d) I 45.Covalent bonding is best descrribed as: a) the equal sharing of electrons b) the repulsion of electrons c) the repulsion of nuclei d) the attraction of two nuclei for each others outer electrons 46.Balance K2SO4(aq) + BaCl2(aq) BaSO4(s) + KCl(aq) 47.Describe in detail solubility. 48.Write the total and net ionic equation when HCl reacts with NaOH: [/QUOTE]
