Question

the lewis dot symbol for the chloride ion is
a)
::a::
b)
::a:
c) cl-
d)
::a.
e)
:a

Explanation:

Lewis dot symbols for ions show valence electrons as dots. Chloride ion (\(Cl^-\)) has 8 valence electrons (gained one electron). It should be enclosed in brackets with a negative charge. Option A correctly shows 8 dots (electrons) around \(Cl\), enclosed in brackets with a negative charge. Option B has incorrect electron count (dots), Option C is just the ion symbol without dots, Option D has incorrect electron count and no brackets, Option E has incorrect electron count.

Answer:

A.
