Will neutron to proton ratio increase or decreases, when a radioactive nucleus emits (i) an alpha particle (ii) a beta particle ? Giveone example for each in support of your answer.

What changes occur in the nucleus of a radioactive element when it emits (a) an alpha particle, (b) a beta particle, ( c) gamma radiation ? Give one example, in each case (a) and (b) in support of your answer.

A radioactive nucleus emits beta particle. The parent and daughter nuclei are

A radioactive nucleus emits a beta particle. The parent and daughter nuclei are:

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

What happens to the position of an element in the periodic table when its nucleus emits (a) an alpha -particle, (b) a beta -particle and (c ) gamma radiation ? Give reason for your answer.

The neutron to proton ratio of the daughter element after a nucleides ""_(92)U^(238) loses an alpha -particle and a beta particle successively is

In a radioactive decay,the nucleus emits an alpha -particle followed by two beta -particles.Show that the final nucleus is an isotope of the original line.

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

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