검증된 단계별 안내1
Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net electric charge.
Recall that chloride ions (Cl^-) are formed when a chlorine atom gains one electron.
Since chlorine gains one electron, it acquires a negative charge equal to the charge of one electron, which is -1.
Therefore, the charge of a chloride ion in a salt compound is represented as Cl^- indicating a single negative charge.
Conclude that the correct charge of chloride ions (Cl^-) is -1.
