alpha -particles and beta -particles

After emission of one alpha particle followed by one beta -particle from ""_(92)^(238)X , the number of neutrons in the atom will be

Amongst alpha,beta and gamma- particles, alpha- particle has maximum penetrating power. The alpha- particle is heavier than beta and gamma- particle.

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 given electric field , the beta particle are deflected more than the alpha -particle in spin of the alpha - particle having a langer charge

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 :

A radiaoactive nucleus (initial mass number A and atomic number Z emits 3 alpha - particles and 2 positrons The ratio of number of neutrons to that of proton in the final nucleus will be

A radiaoactive nucleus (initial mass number A and atomic number Z emits 3 alpha - particles and 2 positrons The ratio of number of neutrons to that of proton in the final nucleus will be
