Definition
- Adjective:
- Not converted into ions: Describes a substance, molecule, or atom that has not gained or lost electrons and therefore carries no net electrical charge. It is the opposite of being ionized.
Usage
The adjective "nonionised" is used primarily in scientific contexts, especially chemistry and physics, to describe the neutral state of matter. It often modifies nouns like "atoms," "molecules," "gases," or "forms." * It is typically used in technical writing, research papers, and educational materials. * The more common spelling in American English is "nonionized."
Examples
- Scientific Description:
- In its nonionised state, the gas is a poor conductor of electricity.
- The study compared the absorption rates of ionised and nonionised minerals.
- Most of the atoms in the cool stellar atmosphere remain nonionised.
Advanced Usage
- "nonionised radiation": Refers to types of radiation, such as ultraviolet or radio waves, that do not have enough energy to remove electrons from atoms or molecules upon interaction, unlike ionizing radiation (e.g., X-rays).
- Mobile phones emit nonionised radiation, which is considered less harmful than ionizing radiation.
Variants and Related Words
- Nonionized (adj): The preferred spelling in American English, identical in meaning to "nonionised."
- Unionized (adj): A homograph (same spelling, different meaning). In scientific contexts, it is pronounced with a long "i" (un-I-onized) and is a synonym for "nonionised." In labor contexts, it is pronounced with a short "i" (UN-yon-ized) and means "belonging to a trade union."
- Ionised/Ionized (adj): The direct antonym, meaning converted into ions.
- Neutral (adj): In a chemical context, can be a near-synonym, describing a particle with no net charge.
