The correct Lewis dot symbol for the chloride ion (Cl⁻) is represented as follows:
Cl:
In this representation, the chlorine atom has seven valence electrons. When it gains one additional electron to form the chloride ion (Cl⁻), it achieves a stable octet configuration. The Lewis dot symbol for the chloride ion is written with the symbol ‘Cl’ surrounded by eight dots, representing the eight valence electrons.
Here is the Lewis dot symbol for the chloride ion:
Cl: with eight dots around it, arranged in pairs on the top, bottom, left, and right sides of the ‘Cl’ symbol.
This configuration shows that the chloride ion has a full outer shell of electrons, making it stable and less reactive compared to the neutral chlorine atom.
