Which option is the chloride ion?

Explanation:
Chloride is chlorine that has gained one electron, giving it a negative charge. In ion notation this is written as Cl-. Gaining one electron completes chlorine’s outer shell, turning it into a stable -1 ion. The other symbols would indicate different charges or species that aren’t the chloride ion (positive Cl+, doubly charged Cl2-, or triply charged Cl3-). The standard chloride ion is Cl-.
