Question

How many valence electrons does the Lewis structure for a chlorine atom show

Answer 1

7 valance electrons the Lewis structure for a chlorine atom show.

Explanation:

Lewis structure is used to keep track of the valance electrons of each atom and share them in bonding. Every valance electron is represented as a dot around the element to keep their count.  

Paired VE’s are shown as ‘:’ and unpaired as ‘.’ in the representation. A chlorine Cl atom has 17 electrons. & of them are valance electrons. Out of the seven six are paired electrons and one is unpaired.  

Answer 2

Answer: D

Explanation:

Chlorine is in group 7 or (VII) in Roman numerals, which means it has 7 balance electrons. It only needs one electron to become stable, hence it is next to the noble gases
