Best Answer: Polyatomic: The only difference between a polyatomic ion and a normal ion is that a polyatomic ion is composed of more than one elements. The elements are chemically bonded and have an overall net charge like a normal ion.
Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di-is of Greek origin, meaning two. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen (O 2), then it is said to be homonuclear.
