Web13 aug. 2024 · The formula of the carbonate ion is CO2 − 3. The atoms of a polyatomic ion are tightly bonded together and so the entire ion behaves as a single unit. The figures below show several examples. Figure 2.5.1: The ammonium ion (NH + 4) is a nitrogen atom (blue) bonded to four hydrogen atoms (white). WebIn case the ion comprises of a mono or single atom, then it is known as the monatomic ion. For instance, let’s consider the hydrogen iron, H + . On the other hand, if the ion …
