WebJun 12, 2024 · Iodine vapour is unequivocally purple. I would assume that astatine behaves like the rest of the halogens in forming dimers, although the calculation could in theory be run for a monomeric vapour too. If you go by Iodine and Bromine vapor, it's probably not a logical stretch to say it would be very dark brown. WebNov 20, 2014 · What is the name of compound for med by sodium and astatine? Sodium astatide, the anion name being formed by the same rule as for all halogens: Change the -ine at the end of the element name to -ide.
