    The correct option is D) it becomes a positive ion.

    Explanation:

    The third shell of the sodium atom has one valence electron. In order to become stable, the sodium atom tends to lose its valence electron so that a stable configuration can be achieved. When a sodium atom loses an electron, the number of protons in the nucleus becomes greater than the number of electrons as one electron has been lost. As a result, the sodium atom becomes a positively charged ion with + 1 charge.
