(d) Ag[Ag(CN)2] Keep in mind, hydrogen can go either way, carrying either a positive or negative charge. Still have questions? 2. These halide ion compounds exist in different forms in nature as solutions, precipitates and solids. They cannot interact effectively, so the crystal lattice is quite easy to break. Because lithium is a cation, it can lower the serum anion gap when present in sufficient concentration (6, 36). Learn vocabulary, terms, and more with flashcards, games, and other study tools. Lithium is commonly prescribed for the treatment of bipolar disorder (6). The metal lithium an electron to form the cation Li' and the nonmetal bromine an electron to form the anion Br.
