Bromine is a wonderfully thick, soupy gas/liquid. Technically it's a liquid at room temperature, but if you have it in the open it will evaporate away at a high rate of speed, evolving clouds of reddish purplish vapor. Confined in a glass ampule, it's a thick dark gas, which is quite odd to look at. Like chlorine, bromine is a highly reactive halogen, choking and toxic to breath, but entirely harmless when in the form of a salt or dissolved ion. People like to soak in sodium bromide solutions (see first sample).

The deep color of this sample is caused by bromine gas, not liquid. There is some liquid condensed on the sides of the bulb, but the majority of the color you see is the gas. I think it's amazing that a gas can be so thick. There's a very similar bulb under chlorine, but its color is much, much lighter. Normally when you see a "gas" that is colored, it's not really a gas but rather tiny droplets of liquid (in fog) or particles (in smoke) that make it look colored or thick. The difference is that in a real colored gas, there is no diffusion of the light, just attenuation. A fog or smoke makes things look fuzzy, while with a true colored gas, they look perfectly sharp, just colored. I received this sample when Tryggvi and Timothy came to my sodium party.

The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table. To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order. For most sample from this set I have my own picture on the left and the one from the company here, but I haven't taken a picture of this sample yet so there's only one picture.

Up until the early 1990's a company in Russia sold a periodic table collection with element samples. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. The samples (excepted gasses) weight about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid.
