Title: What is the "predominantly covalent" compound?
Post by: 33seven on September 22, 2010, 04:14:32 PM

a) Al₂P₃  b) SCl₂  c) PbO  d) Ga₂N₃  e) SnBr₄

I honestly had no idea what to do on this problem so i just guessed Al₂P₃. I found out the answer is SCl₂, but i dont understand why?

Just think about the differences of electronegativity between these atoms... the more the difference is high the more the bond is ionic.
