Understand the definitions of ions: Ions are atoms or molecules that have gained or lost electrons, resulting in a net electric charge.
Recall that cations are positively charged ions formed by the loss of electrons, not negatively charged ions.
Recall that anions are negatively charged ions formed by the gain of electrons, not by the loss of electrons.
Recognize that ions do not have a neutral charge; they have either a positive or negative charge due to the imbalance between protons and electrons.
Conclude that the true statement is: 'An ion is an atom or molecule that has gained or lost electrons.'
