⚡
Add to dictionary

ionized

 

[ˈaɪənaɪzd ]

Definition

Context #1 | Adjective

science, chemistry

Ionized refers to atoms or molecules that have gained or lost one or more electrons, resulting in a net electrical charge. This process can occur due to various factors, including high energy exposure, such as heat, radiation, or electrical fields. Ionization is a fundamental concept in chemistry and physics, as it affects the chemical behavior and properties of substances. Understanding ionization is crucial in fields such as plasma physics, electrochemistry, and atmospheric science.

Synonyms

charged, electrically charged.

Examples of usage

  • Ionized gases are commonly found in stars.
  • The air becomes ionized during a lightning strike.
  • In ionized water, the pH levels may change significantly.
