Ionization

Part of speech: noun

Pronunciation: /ˌaɪənɪˈzeɪʃən/

Definitions

1. The conversion of neutral atoms or molecules into charged particles occurs through the gain or loss of electrons, resulting in the formation of ions
2. This phenomenon describes the process by which atoms or molecules become ions through the exchange of charged particles, affecting their overall charge
3. The process in which atoms or molecules transform into ions by gaining or losing one or more electrons results in charged species

Etymology: Michael Faraday coined the root of this word in the 1830s, when he needed a name for the charged particles that travel through electrolytes. He took the Greek "ión", the present participle of "eimi" (to go), meaning "going," and the word "ion" entered English in that sense. Faraday's coinage gave scientists a way to describe atoms that carry an electrical charge after gaining or losing electrons. "Ionize" was formed by adding the verb-forming suffix "-ize", borrowed from Greek through Late Latin and Middle French, to "ion". The noun "ionization" then adds "-ation", which comes from Latin "-ātiō" through Old French, to turn that action into a process. So the word is a modern scientific coinage built entirely from classical parts, not a term the ancient Greeks would have recognised.
