ions
/ˈaɪ.ɒnz/
Definition
Electrically charged atoms or groups of atoms that result from the gain or loss of electrons, which facilitate chemical reactions.
Etymology
Derived from the Greek word 'ion,' meaning 'going,' which is the present participle of 'ienai' (to go). It was coined by scientist Michael Faraday in 1834 to describe the particles that 'go' toward electrodes in an electrolytic cell.
In the news
In this article, ions are mentioned in the context of concrete production, where injected carbon dioxide reacts with them to create a binding agent that strengthens the material. This highlights the chemical utility of captured carbon in industrial manufacturing.
