Definition
Meaning
A former name for the radioactive chemical element radon (Rn).
A term used in early 20th-century scientific literature for the element now known as radon, particularly the isotope radon-222, as a product of radium decay. The name comes from the Latin 'nitens', meaning 'shining'.
Linguistics
Semantic Notes
This term is entirely obsolete in modern science. It is now purely a historical curiosity found in early publications on radioactivity. It refers specifically to the gaseous radioactive element produced by the decay of radium.
Dialectal Variation

FAQ
Frequently Asked Questions
No, it is an obsolete scientific term. You only need to know 'radon'.
The International Union of Pure and Applied Chemistry (IUPAC) standardized the name 'radon' to align with the naming convention of other noble gases (ending in -on) and to reflect its origin from radium.
No, it would be considered incorrect. Always use the modern standard name 'radon'.
Only in historical documents, early 20th-century textbooks, or in discussions about the history of chemistry and the discovery of radioactivity.
