Researchers have discovered that sunlit snow is the major source of atmospheric bromine in the Arctic, the key to unique chemical reactions that purge pollutants and destroy ozone. National Science ...

Scientists followed a bromine chemical bond as it broke apart using an image that was obtained from a single molecular orbital. The experiment used an attosecond-duration X-ray burst to take a ...

Chemistry has many laws, one of which is that the rate of a reaction speeds up as temperature rises. So, in 1989, when chemists experimenting at a nuclear accelerator in Vancouver observed that a ...

Molten lead(II) bromide can be broken down into lead metal and bromine gas, and lithium chloride can be broken down into lithium metal and chlorine gas. Oxygen and hydrogen gases can be obtained from ...
