Melting and boiling points of halogens
Web29 okt. 2024 · I'm helping a friend with their GCSE exams. There was a mock question that had the melting points of all the halogens except for Chlorine. They had to estimate the melting point of Chlorine from the other halogens. Firstly, if Chlorine's melting point is omitted as in the test, from the graph it looks like it should be -150 o C.
