Definition
- Adjective:
- Converted totally or partly into ions: Describes a substance, typically a gas or a solution, that has been transformed so that some or all of its atoms or molecules have gained or lost electrons, thus acquiring a net electric charge.
Usage
- The term "ionised" is used to describe the state of matter after it has undergone ionisation. It is commonly applied in scientific contexts, particularly in physics and chemistry, to discuss plasmas, electrolytes, and radiation effects.
- Note on Spelling: "Ionised" is the British English spelling. The American English spelling is "ionized".
Examples
- Adjective:
- The experiment required an ionised gas to conduct electricity.

Advanced Usage
- "Fully ionised": Describes a state where all atoms in a substance have lost or gained electrons.
- In the core of the sun, matter exists as a fully ionised plasma.
- "Partially ionised": Describes a state where only a fraction of the atoms or molecules are charged.
