Melting point and boiling point graph
Web10 jul. 2015 · The boiling points of group 13 and 14 elements decrease down the group, which is opposite to the trend suggested by van der Waals interactions. I suspect that the increase in melting point results from the change in crystal structure and the increasing metallic character of the elements as you go down the group. $\endgroup$ – Web1 jun. 2024 · To build Model 2, we have analyzed melting points of 1500 molecules, which are listed in Table S2 in the Supporting Information.
