` alpha`-particles and ` beta`-particles

._(92)U^(238) emits 8 alpha- particles and 6 beta- particles. The n//p ratio in the product nucleus is

A radioactive nucleus ._(Z) X^(A) emite 3 alpha- particles and 5 beta - particles . The ratio of number of neutrons to that of protons in the producet nucleus will be :

In a radioactive decay chain, the initial nucleus is overset(232)(90).^(Th) . At the end there are 6 alpha -particles and 4 beta -particles which are emitted. If the end nucleus is overset(A)(Z).^(X),A and Z are given by :

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

A nucleus ._(Z)X^(A) emits 2 alpha - particles and 3 beta - particles. The ratio of total protons and neutrons in the final nucleus is :

Successive emission of an alpha -particle and two beta -particles by an atom of an element result in the formation of its
