A compound contains atoms of different elements, chemically joined together. Compounds form in chemical reactions, and you need other chemical reactions to separate a compound into its elements.

Beyond the fact that the radio-elements were in present course of evolution, it added little to the conceptions of chemistry. But in the second and more recent phase—concerned with the chemical ...

Researchers at MSU found that H₃⁺ can form in unexpected ways. They studied molecules hit by high-energy light.

KIT researchers lay the foundation for new materials and chemical processes by synthesizing an unusual molecule. Researchers ...
