There are a zillion. Simply put, a polyatomic ion is an ion with two or more atoms in it. (Polyatomic is "multi" atom.) The number "zillion" isn't specific, of course, but we might be able to use it here in the science section to make a point. The phosphate group, PO4-2, and the hydroxyl group, OH-, are just two of many, many polyatomic ions. A link can be found below to the Wikipedia article on polyatomic ions. You'll find a looong list of them there. Why not check it out?
Ions made up of more than one atom are called polyatomic ions.
There are two such ions: Hydronium (H3O+) and hydroxide (OH-).
No. Most polyatomic ions are anions.
Except chloride, all others are polyatomic ions.
polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
An ion that is made up of more than one atom.
Covalent bonding is predominantly within polyatomic ions.
The polyatomic ion for Ammonium is NH4+
They are not similar.
For example no3 or co3 are all polyatomic ions
A polyatomic ion is charged and will form ionic bonds; for example, the sulfate ion SO42- forms many compounds, such as sodium sulfate. The bonds holding polyatomic ions together are covalent.
