In a nuclear decay, a nucleus emits one `alpha`-particle and then two `beta`-particles one after another. Show that the final nucleus is an isotope of former nucleus.

In a radioactive disintegration a nucleus emits an alpha -particle first and then two beta -particles. Show that the final nucleus thus formed is the isotope of the first.

A nucleus ._n^mX emits one alpha particle and two beta^- particles .The resulting nucleus is

If a radioactive element emits - (i) alpha -particle and (ii) beta -particle, then how its mass number and atomic number will change?

When an alpha - particle is emitted from a uranium nucleus (atomic no. 92, mass number 238), a new nucleus is formed. From this nucleus a beta -particle is also emitted. Wha will be the atomic number and mass number of the final nucleus ?

If an alpha -particle and two beta -particles are emitted from from a radioactive element, the element produced becomes an ____of the parent element.

A radioactive atom _(Y)^(X) M emits two alpha particles and one beta particle successively. The number of neutrons in the nucleus of the product will be

Which one of the following types of cells lack nucleus in humans ?

A radioactive nucleus of mass number A, initially at rest, emits an alpha -particle with a speed v. The recoil speed of the daughter nucleus will be

For the radioactive nuclei that undergo either alpha or beta decay, which one of the following cannot occur? (A) Isobar of original nucleus if produced (B) Isotope of the original nucleus is produced (C) Nuclei with higher atomic number than that of the original nucleus is produced. (D) Nuclei with lower atomic number than that of the original nucleus is produced.

From the nucleus of a Polonium atom ._84Po^218 , an alpha -particle and two beta -particles are emitted successively due to radioactive disintegration. What will be the nuclei produced in these steps ?
