A molecule is neutral, an ion has an electrical charge.
Ions made up of more than one atom are called polyatomic ions.
structural formula
polyatomic ionsFor example, ammonia, NH3, forms the polyatomic ion NH4+.
They are molecules.No they are generally called molecules. However there are polyatomic ions that are charged molecules, such as SO42-
Ionic compounds contain ions, there are no neutral molecules. These are often charged atoms as in NaCl but may be polyatomic ions such as NH4+ which contains covalent bonds
The general term is fairly straightforward, if you know a little Greek: polyatomic ions.
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.
Covalent bonding is predominantly within polyatomic ions.
The polyatomic ion for Ammonium is NH4+
They are not similar.
