When an atom that has no charge loses two electrons, it becomes a 1. positive ion. 2. negative ion. 3. positive isotope. 4. negative isotope.

Answer;

1. positive ion

Explanation;

-An ion is formed when an atom gains or looses electrons. A positively charged ion (cation) is formed when an atom looses electrons and a negatively charged ion (anion) is formed when an atom gains electrons. Therefore, if an atom looses two electrons it forms a positively charged ion with a charge of +2.
