Which statement best describes alpha decay?(1 point)

After the ejection of an alpha particle, the remaining nucleus has a mass number that is two less and an atomic number that is two less, so alpha decay is a type of nuclear fission.

After the ejection of an alpha particle, the remaining nucleus has a mass number that is two less and an atomic number that is two less, so alpha decay is not a type of nuclear fission.

What is nuclear fission?

Nuclear fission is the disintegration of a radioactive material into smaller elements.

In radioactivity, there are various particles as follows:

  • alpha particle
  • Beta particle
  • Gamma particle

Alpha particle is characterized by the possession of mass number of 4 and atomic number of 2 i.e. He⁴/2.

Therefore, if a substance undergoes alpha decay, the remaining nucleus has a mass number that is four less and an atomic number that is two less, so alpha decay is a type of nuclear fission.
