What is the position of daughter nucleus in the periodic table in relation to the parent nucleus if an `alpha`-particle is lost from the parent?

Text Solution

Verified by Experts

The correct Answer is:
The daughter nucleus has its atomic number reduced by 2 units and mass number reduced b6 4 units than that of the parent nucleus.

A : If a stationary nucleus emits an alpha -perticle , the de Broglie wavelengths of te daugther nucleus and the alpha -perticle and equal . R : The magnitudes of the linear moments of the daughter nucleus and the alpha -perticle are the same .

A : During radioactive disintegration an alpha -particle and a beta -particle do not emit simultaneously from any nucleus. R : An alpha -particle emits from a nucleus when the N/Z ratio is less than the stability range (where N=number of neutrons and Z=number of protons in a nucleus. )

The number of neutrons in the parent nucleus which gives N^14 on beta -emission and the parent nucleus is
