FAQ

Frequently Asked Questions

No, it is not a stable compound. It is a historical term for a hypothetical radical (NH₂ or NH) considered in early structural chemistry.

It is strongly discouraged. Modern IUPAC nomenclature (e.g., 'amino group', 'azanyl') should be used instead for clarity and precision.

Ammonia (NH₃) is a stable molecule. Amidogen refers to the theoretical radical fragment (NH₂) that would remain if a hydrogen atom were removed from ammonia.

Dictionaries record historical and technical vocabulary to aid in understanding older texts and the development of scientific language.
