We are asked to determine the number of electrons gained when chlorine achieves a stable electron configuration.


To do this, we shall first write the electron configuration.

We can determine the ground-state electron configuration of Chlorine (Cl) by referring to the periodic table and locating the position of Cl in the periodic table.

Ground-state means that the element is in its lowest energy form (not in excited state).
