QUESTION:
What are the basic units—single atoms, molecules, or formula units—that compose each substance?
(a) \(\mathrm{Rb}_{2} \mathrm{O}\)
(b) \(\mathrm{N}_{2}\)
(c) \(\mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{2}\)
(d) \(\mathrm{~N}_{2} \mathrm{~F}_{4}\)
ANSWER:Step 1 of 5
\(\mathrm{Rb}_{2} \mathrm{O}\), or rubidium oxide, is an ionic compound. In ionic compounds, the basic unit that makes up the structure is known as a formula unit. In the case of rubidium oxide, the formula unit consists of rubidium ions \(\left(\mathrm{Rb}^{+}\right)\) and oxide ions \(\left(\mathrm{O}^{2-}\right)\). These ions are held together by ionic bonds. Unlike molecules, formula units represent the simplest ratio of ions involved but don't exist as discrete entities.
