32. As in other liquids, the attractions between water molecules are strong enough to keep them the _____________ but weak enough to allow each molecule to be _____________ the attractions that momentarily connect it to some molecules and _____________ to other molecules. 33. To write the name that corresponds to a formula for a compound, you need to develop the ability to recognize the formula as representing a(n) ____________. 34. You can recognize binary covalent compounds from their formulas, which contain symbols for only two _____________ elements. 35. Metallic atoms hold some of their electrons relatively loosely, and as a result, they tend to _____________ electrons and form cations. In contrast, nonmetallic atoms attract electrons more strongly than metallic atoms, so nonmetals tend to _____________ electrons and form anions. 36. Nonmetallic atoms form anions to get the same number of electrons as the nearest _____________. 37. The names of _____________ always start with the name of the metal, sometimes followed by a Roman numeral to indicate the charge of the ion. 38. When atoms gain electrons and form anions, they get _____________. When atoms lose electrons and form cations, they get significantly _____________. 39. The ions in ionic solids take the arrangement that provides the greatest _____________ while minimizing the _____________. 40. It is common for hydrogen atoms to be transferred from one ion or molecule to another ion or molecule. When this happens, the hydrogen atom is usually transferred without its electron, as _____________. 41. Ionic compounds whose formula contains one symbol for a metal and one symbol for a nonmetal are called _____________ ionic compounds.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
