Question

What are all the Lewis symbols for Cl?

Answer 1

All one of them? Chlorine atom has `7` valence electrons. I shall attempt to draw this using math!

`cdotddot"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 -> 9:00`.

On the 7th valence electron we thus land on `6:00`.
