Study the diagram of radioactive decay. Which option identifies what the arrows in the diagram represent? atoms and elements ele
2 answers:
Energy and particles are produced from the radioactive decay.
By studying the diagram of radioactive decay we identifies two materials i.e. energy and particles which are the two products emitting from the radioactive source.
From radioactive decay, radiation is emitting in the form of alpha, beta and gamma radiation as well as the production of particle that is stable without radiation so we can conclude that energy and particles are the two products produced from the process of radioactive decay.

The arrows in the image represent energy and particles.
Radioactive decay involves the disintegration of a nucleus to yield smaller nuclei with the emission of energy. The process may occur spontaneously for large nuclei or it may be induced by bombardment with other particles.
We know that radioactive decay leads to;
- Formation of new nucleus/nuclei
- Emission of energy
- Emission of particles
Therefore, the arrows in the image represent energy and particles.
