The most important series, including water, has the chemical formula H2X, with X representing any chalcogen. They are therefore See more

Dihydrogen dichalcogenides have the chemical formula H2X2, and are generally less stable than the monochalcogenides, commonly decomposing into the monochalcogenide and the chalcogen involved.
The most important … See more

Some monohydrogen chalcogenide compounds do exist and others have been studied theoretically. As radical compounds, they are quite unstable. The two simplest are See more

All straight-chain hydrogen chalcogenides follow the formula H2Xn.
Higher hydrogen polyoxides than H2O2 are not stable. Trioxidane, with three oxygen atoms, is a … See more
