Question

when an atom that has no charge loses two electrons, it becomes a positive ion. negative ion. positive isotope. negative isotope.

Explanation:

Electrons are negatively - charged particles. When a neutral atom loses electrons, it has more protons (positively - charged) than electrons, resulting in a positive charge. An ion is an atom or molecule with a net electric charge. Isotopes are atoms of the same element with different numbers of neutrons, not related to electron - loss charge changes.

Answer:

A. positive ion
