Which lewis structure below correctly represents kcl? which lewis structure below correctly represents kcl? none of the above?

Following is the correct Lewis structure of Potassium Chloride.

Reason:

In Lewis structure only the valence electrons are shown, As K belongs to First group in periodic table so it has one valence electron and shown as + in structure. While, Chlorine belongs to Seventh group and has 7 valence electrons and are shown in structure with ⁰ in lewis structure below.
