The statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.
To determine if the statement is true or false we need to know what radiactivity is
What is radioactivity?
Radioactivity is the spontaneous disintegration of unstable atomic nuclei to form stable more energetic nuclei with the emission of radiation.
Radioactivity includes the following
- disintegration of a larger atomic nuclei to a smaller more stable nuclei
- Emission of radiation
So, radioactive nuclei which are unstable emit radiation and become more stable.
So, the statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.
