Can an atom have more than 8 valence electrons? If not, why is 8 the limit?
I was watching this youtube clip ( http://www.youtube.com/watch?v=XY1XLgHUAIQ ) in which a lewis diagram was drawn for a sulfite ion.
Sulfur ends up with four bonds as well as a lone pair of electrons. This gives sulfur 10 electrons. Isn't this too many?
