Explanation:
A radioactive decay is defined as the process where an unstable nuclei of an atom loses energy by releasing particles like alpha or beta particles.
For example, [tex]^{235}_{92}U \rightarrow ^{231}_{90}Th + ^{4}_{2}He + Energy[/tex]
Here, [tex]^{4}_{2}He[/tex] is an alpha particle. This shows that above radioactive decay has released alpha particle along with release of energy.
When we show this radioactive decay diagrammatically then arrows are used to depict the release of energy and particles.
Thus, we can conclude that the arrows in the diagram represent energy and particles.
