Respuesta :

A positively charged sodium ion which has lost an electron 

Answer;

-a positively charged sodium ion

Explanation;

-Ions are formed when atoms of elements looses or gains electrons. Positively charged ions (cations) are formed when an atom usually a metal atom looses electrons, while a negatively charged ion (anion) is formed when an atom (non metal atom) gains electrons.

-Sodium being a metal forms a positively charged ion (cation) by loosing one electron to attain a stable configuration. The symbol of sodium ion is Na+,which shows that it has lost one electron to become a positively charged ion.
