Question

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

Explanation:

An atom with no charge (neutral) has equal protons (positive charge) and electrons (negative charge). When it loses two electrons, the number of protons (positive) becomes greater than electrons (negative). Ions are charged atoms; positive ions (cations) have more protons than electrons. Isotopes relate to neutron number, not electron loss. So losing electrons makes it a positive ion.

Answer:

A. positive ion.
