What is the "predominantly covalent" compound?
« 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.
