What is the charge of chloride ions (Cl^-) when present in a salt compound?

• A. -2
• B. 0
• C. -1
• D. +1

Answer: (C)

Verified step by step guidance

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