Question

Are chloride ions positively or negatively changed? How do you know this? Please explain?

Answer 1

Chloride ions (Cl-) are negatively charged. They have gained an extra electron, giving them a negative charge. In chemistry, ions are classified based on whether they have lost or gained electrons. In the case of chloride ions, they have gained an electron from a neutral chlorine atom, resulting in a negative charge.

Chlorine has 7 valence electrons in its valence shell thus it gains one more electron to complete octet and become more stable.

Hope that helps
