No, a polyatomic ion cannot exist by itself because it carries an overall charge due to the presence of multiple atoms with varying electron configurations. These ions are stable only when they are associated with other ions to maintain overall neutrality in a compound.
Sodium perbromate is not a polyatomic ion. It is an ionic compound formed by combining sodium (Na +1 ) ions with perbromate ions (BrO4 -1). Perbromate by itself would be a polyatomic ion.
The polyatomic ion is the ammonium ion, NH4^+
The polyatomic ion for nitrite is NO2-.
The polyatomic ion is a carbonate ion, with formula CO3-2.
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
The hydroxide ion (OH⁻) is a polyatomic ion itself, consisting of one oxygen atom and one hydrogen atom. Therefore, it can be said that there is one polyatomic ion in OH. Polyatomic ions are characterized by containing multiple atoms, and in this case, OH qualifies as such.
Sodium perbromate is not a polyatomic ion. It is an ionic compound formed by combining sodium (Na +1 ) ions with perbromate ions (BrO4 -1). Perbromate by itself would be a polyatomic ion.

A polyatomic ion.
The polyatomic ion SO5 does not exist. The closest polyatomic ion to this is SO4^2- which is called sulfate ion.
The polyatomic ion for nitrite is NO2-.
The polyatomic ion is a carbonate ion, with formula CO3-2.
yes it is polyatomic ion because it is made up of more than 2 atoms
Calcium hydroxide, Ca(OH)₂, is not considered a polyatomic compound itself, but it contains a polyatomic ion, hydroxide (OH⁻). In this compound, two hydroxide ions are bonded to a calcium ion (Ca²⁺). Therefore, while Ca(OH)₂ is an ionic compound, it includes a polyatomic ion within its structure.
KOH is an ionic compound with a polyatomic ion. The hydroxide ion (OH-) is a polyatomic ion that is composed of one oxygen atom and one hydrogen atom.
The polyatomic ion is a carbonate ion, with formula CO3-2.
This is the ion acetate.
