At high concentrations, HF molecules undergo homoassociation to form polyatomic ions ( such as bifluoride, ) and protons, thus greatly increasing the acidity.
32.
The two notations are, therefore, exchangeable for monatomic ions, but the Roman numerals " cannot " be applied to polyatomic ions.
33.
However, it is possible to mix the notations for the individual metal centre with a polyatomic complex, as shown by the uranyl ion example.
34.
Polyatomic and molecular ions are often formed by the gaining or losing of elemental ions such as a proton, H +, in neutral molecules.
35.
Formaldehyde was the first polyatomic organic molecule detected in the interstellar medium and since its initial detection has been observed in many regions of the galaxy.
36.
An example of a polyatomic dication is, formed by oxidation of S 8 and unstable with respect to further oxidisation over time to form SO 2.
37.
For polyatomic molecules there is more than one bond, and the total molecular dipole moment may be approximated as the vector sum of individual bond dipole moments.
38.
I'm doing my science homework and I've been learning about Polyatomic Ions in class and now we're practicing writing formulas and nomenclature.

Ions consisting of only a single atom are atomic or monatomic ions; if they consist of two or more atoms, they are molecular or polyatomic ions.
