Why does chlorine have a higher boiling point than krypton?

To determine why chlorine's melting point (-100.98) is higher than krypton's melting point (-157.2), you must look at the electron configuration of the elements. 36Kr: [Ar]4s23d104p6, and 17Cl: [Ne]3s23p5. There is a trend in the periodic table that states that elements with paired electrons in the electron orbitals will have extremely low melting points (why all noble-gases have low melting points). So since krypton is a noble-gas, it has every electron orbital filled, forming an octet, therefore having a lower melting point. Chlorine, has a 3p5 orbital and therefore not completing the octet, or paired p-orbital, therefore having a higher melting point.
