 | | A negatively charged ion, which has more electrons in its electron shell than it has protons in its nucleus, is known as an anion, for it is attracted to anodes, and a positively charged ion, which has fewer electrons than protons, is known as a cation (pronounced cat-eye-on), for it is attracted to cathodes. |
 | | A collection of non-aqueous ions, or even a gas containing a proportion of charged particles, is called a plasma, which is called the fourth state of matter because its properties are quite different to solids, liquids, and gases. |
 | | The word ion is a name given by Michael Faraday, from Greek ἰόν, neutral present participle of ἰέναι, "to go", thus "a goer". |
