Web29 okt. 2024 · 0. 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. WebMelting Point: -101.5°C, -150.7°F Boiling Point: -34.04°C, -29.27°F Discovered by: Carl Wilhelm Scheele produced the gas in 1774, but it was Sir Humphry Davy who first called it an element and named it chlorine in 1810 Chlorine is the second element in the seventeenth column of the periodic table.
