A large unstable nucleus becomes tinier and emits an alpha particle during Alpha decay. 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay. It has a charge of positive 2.

Answer: The product of the radioactive decay [tex]_2^4\textrm{He}[/tex] is called as alpha particle.

Explanation:

Radioactive decay of the nuclei happens when a nuclei has to attain some sort of stability. It undergoes various decay processes and releases various particles during these decay process. The types of particles released are:

  1. Alpha particle: These are released during alpha decay. The particle released carry a mass of +4 units and a charge of +2 units. It is represented as [tex]_2^4\alpha[/tex]
  2. Beta particle: These are released during beta decay. The particle released carry a mass of 0 units and a charge of -1 units. It is represented as [tex]_{-1}^0\beta[/tex]
  3. Gamma particle: These are released during gamma decay. The particle released does not carry any charge and is electrically neutral. It is represented by [tex]\gamma -\text{particle}[/tex]

Hence, the correct answer is alpha particle.
