Step 1:: Recall the valence electrons rule for Lewis structures.
In Lewis structures, we need to account for the valence electrons of each atom. For chlorine (Cl), which is in the 17th group of the periodic table, the valence electron configuration is ns^2 np^5. This means that chlorine has 7 valence electrons.
Step 2:: Draw a single chlorine atom with its valence electrons.
We will represent each electron as a small dot around the chlorine atom. Cl : • • • • • •
Step 3:: Place the valence electrons to form an octet around the chlorine atom.
To do this, we will move six of the electrons around the chlorine atom to form three pairs. Cl : • • • • • •
Step 4:: Finalize the Lewis structure for chlorine.
We have now placed all 7 valence electrons around the chlorine atom, forming an octet.
Final Answer
Cl : • • • • • •
