Highest melting point of elements
Web27 de fev. de 2024 · Coming to the trend in boiling points now. Part of the difference in the trend has to arise from the excessively large melting point of boron. You see, thallium boils off even when boron has yet to melt, so that is a contributing factor in the excessively large boiling point of boron over the others. According to this paper [1], for liquid ...
