Title: Why does Sodium Have a lower melting point than Octasulfur (S8)?
Post by: bananabandana on November 26, 2013, 04:16:22 PM

I'm confused by this. I thought the metallic bonding in Sodium would be much stronger than the Van Der Waals attraction of S8 moleculues?

 I think sulphur forms polymere chains (ß-sulfur), if it get molted. It is not a matter of van de Waals.
