Melting point down group 17
Web19 sep. 2024 · The general melting point decreases as we move down the group, this is because of the changing forces of attraction for the differing elements. Down the group, the electrons are further from the nuclei of the increasingly large positive ions. This makes the metallic bonding weaker, reducing the melting temperature. Web7 jan. 2024 · What is the trend in melting and boiling points as we go down the group 17 elements? The melting and boiling points increase down the group because of the van der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
