D) O A chemical reaction is the process used to describe a chemical change. Covalent compounds are molecular, composed of electrically neutral groups of atoms bound together by covalent bonds. We can solve the problem in one of two ways: (1) compare the relative positions of the four possible reductants with that of the Ag 2 S/Ag couple in Table 1 or (2) compare E for each species with E for the Ag 2 S/Ag couple (0.69 V). The following alternatives also exist: L4-L5-S1-Ala. L4-L5-Ala. 7. The number at the top of each representative family is the same as the number of outer orbital electrons (with the exception of helium). Covalent compounds are molecules of two or more nonmetal atoms held together by a covalent bond. Ionic compounds formed by ions of the transition elements, which can have a variety of charges, have an additional rule to identify which variable-charge ion is involved.
