They are both ions and both can form an ionic compound
Molecules are atoms almost constantly bind to each other in nature to form groups.
Polyatomic ions are covalently bonded groups of atoms that have a positivie or negative charge and acts as a unit.
They are similar because they both contain groups of atoms.
The polyatomic ion for Ammonium is NH4+
Polyatomic ions act like an ion other than they travel in groups of ions. It will respond the same like any other ion.
For example no3 or co3 are all polyatomic ions
They are not similar.
If the compound contains a polyatomic ion, simply name the ion.
If the compound contains a polyatomic ion, simply name the ion.
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.
NH4+ ion is ammonium ion
The atoms in a polyatomic ion are held together with covalent bonds, but polyatomic ions combine with ions of opposite charge to form ionic compounds.

Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
