# What are all the Lewis symbols for Cl?

All one of them? Chlorine atom has $7$ valence electrons. I shall attempt to draw this using math!
$\cdot \ddot{\text{Cl}} :$
""^(color(white)(....)ddot)
Traditionally, one distributes the valence electrons across the atom, then switches axes, then goes clockwise, i.e. $12 : 00$, $6 : 00$, $3 : 00$, $9 : 00$, then $12 : 00 \to 9 : 00$.
On the 7th valence electron we thus land on $6 : 00$.
