What is the difference between polyatomic ions and binary ionic compounds?
A polyatomic ion is a group of atoms bond by covalent bonds with an unbalanced charge.
A binary ionic compound is composed of atoms of two elements bond by an ionic bond.
Polyatomc ions are charged compounds composed of non-metals with covalent bonds created by gaining or losing electrons to form the bonds. This creates an unbalanced charge. Examples include:
A binary ionic compound is composed of the atoms of two (bi) elements bond by ionic bonds.
