Group ions contain two or more atoms and usually have a negative charge. The formulae of these ions can be found in the data booklet. We can take the number of charges on the ion as the valency of ...

The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The ...

Gas-phase ion chemistry is a fascinating area of study that focuses on the interactions and reactions of ions in the gas phase. This field is particularly important for understanding the ...

Würzburg chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a ...

The interplay between the intimate coordination chemistry of each family of sites and the changing metabolic needs of the cell may well prove to be a key to unlocking the roles of metal ions in ...

Copper ions in solution moving between two electrodes in a magnetic field produce a swirling motion that can easily be displayed on an overhead projector. Place some pepper on the surface of the ...

Chemists have succeeded in controlling the passage of halide ions by deliberately introducing defects into a two-layer nanographene system. Their paper shows new perspectives for applications in water ...
