which is a characteristic of all ions?\nthey are metals.\nthey have a charge.\nthey are made of two or more types of atoms.\nthey form chemical bonds through electron sharing.
Answer
Brief Explanations:
An ion is an atom or molecule that has a net electrical charge due to the loss or gain of electrons. Not all ions are metals. Ions can be single - atom or poly - atomic. Chemical bonds formed through electron sharing are covalent bonds, not a characteristic of all ions.
Answer:
They have a charge.
