Melting and boiling points of halogens
Web2 nov. 2024 · The atomic size of halogens increases on moving down the group and hence the strength of van der Waals forces between the molecules also increases. In the lighter elements, F and Cl, these forces are weak, hence they are gases at room temperature and possess low melting and boiling points. WebThe halogens are a group in the periodic table systematically known as group 17. It consists of fluorine, chlorine, bromine, iodine, astatine, and tennessine. The halogens generally show many of the properties typical of non-metals. They are poor conductors and have low melting and boiling points.
