What happens when a sodium atom loses an electron in its outer energy

O

A. It becomes a negative ion

O

B. It has an increase in the number of protons.

O

C. It has an increase in the number of neutrons.

O Dit becomes a positive ion.

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.
