But why does bromine have a higher boiling point than krypton?
Is it because bromine exists as Br2 and each molecule is much bigger than a krypton atom (which i think exists singularly cause its a noble gas)

Bromine is a molecule so it has more electrons => stronger induced dipole-dipole forces?

/QUOTE]

Also I think Se has the highest boiling point and is a solid because it might be like S8 (same group) which is an even bigger molecule than bromine so will have the highest boiling pooint
