Krypton and bromine
WebBromine is toxic and reactive. Materials 2 sealed tubes with bromine in a ½ atmosphere and bromine in a vacuum Beaker with dry ice Procedure Before class, the 2 tubes are placed into the beaker of dry ice. When removed the tube in the atmosphere slowly diffused up while the vacuum tube uniformly darkens as the bromine moves into the gas phase. Web30 okt. 2015 · On the other hand, in krypton's case, the incoming electron must be added to the next energy level, n=5, which is so energetically unstable that energy must be provided in order to make this happen. This is why krypton's electron affinity is negative -> you'll sometimes see it listed as 0, like you can see in the above graph.
