WebFor this discussion, the terms "molecule" and "molecular geometry" pertain to polyatomic ions as well as molecules. Molecular Orbitals When two or more atoms approach each other closely enough, pairs of valence shell electrons frequently fall under the influence of two, and sometimes more, nuclei. Electrons move to occupy new regions of space ... WebJul 29, 2024 · Polyatomic Ions. The ions that we have discussed so far are called monatomic ions, that is, they are ions formed from only one atom. We also find many polyatomic ions. These ions, which act as discrete units, are electrically charged molecules (a group of bonded atoms with an overall charge). Some of the more … simply unscented

WebAug 13, 2024 · The carbonate ion (see figure below) consists of one carbon atom and three oxygen atoms and carries an overall charge of 2 −. 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.
