which is a characteristic of all ions?\no they are metals.\no they have a charge.\no they are made of two or more types of atoms.\no they form chemical bonds through electron sharing.
Answer
Brief Explanations:
Ions are atoms or groups of atoms that have gained or lost electrons, resulting in a net electrical charge. They can be metals or non - metals, and not all are made of multiple types of atoms. Chemical bonds through electron sharing are covalent bonds, not a characteristic of ions. The defining feature of ions is having a charge.
Answer:
They have a charge.
