Respuesta :
The radioactive are referred to as parents atoms; the atoms they disintegrate to form are called daughter products. Some isotopes release an alpha particle during nuclear disintegration; an alpha particle consists of two protons and two neutrons (equivalent to the nucleus of an atom of helium).
Answer:
Helium
Explanation:
An alpha particle is a particle that is emitted during radioactive decay.
The particle consists of two protons, and two neutrons.
The reason that an alpha particle can also be referred to as a Helium nucleus, is because the Helium atom consists of two protons, two neutrons, and two electrons. The nucleus only contains protons and neutrons, hence a Helium nucleus would consist of the same material as an alpha particle (two protons and two neutrons).
