    For the melting point, the stronger the forces that act between molecules of a substance, the higher the melting point tends to be.

    To see the detail of the trend of melting point on the periodic table, refer to this website: http://antoine.frostburg.edu/chem/senese/101/perio... terms of chemical reacitivity's trend, which increases from right to left, up to down.

    天啊~ 好麻煩

    知識+對於知識補充問題可不可以不要這樣啊

    只是補充問題修修改改而以嘛!!

    Source(s): 為什麼知識+變成這樣? 之前寫的改不了?
