Answer
The correct statements are "Polyatomic ions have one overall charge," "Polyatomic ions attract other ions to form ionic bonds," and "Polyatomic ions are made up of two or more types of atoms."
Explanation
Polyatomic ions are ions that consist of two or more atoms covalently bonded or of a metal complex that acts as a single unit with a net charge on the ion. The first statement, "Polyatomic ions have many charges," is not accurate. Although a polyatomic ion is composed of multiple atoms, it does not have multiple charges. Instead, it carries one overall charge, which is distributed over the entire ion. The second statement, "Polyatomic ions have one overall charge," is correct. Despite being composed of multiple atoms, a polyatomic ion carries a single net charge. The third statement, "Polyatomic ions repel other ions to form ionic bonds," is incorrect. In fact, polyatomic ions, like all ions, are attracted to ions of the opposite charge. This attraction leads to the formation of ionic bonds.The fourth statement, "Polyatomic ions attract other ions to form ionic bonds," is correct. Polyatomic ions, like all ions, form ionic bonds by attracting ions of the opposite charge.The fifth statement, "Polyatomic ions are made up of only one type of atom," is incorrect. By definition, polyatomic ions are composed of two or more types of atoms.The sixth statement, "Polyatomic ions are made up of two or more types of atoms," is correct. This is the definition of a polyatomic ion.
