In the radioactive disintegration of `"_A^ZX` n alpha-particles are emitted . Find atomic number and mass number of the new nucleus formed by this disintegration?

A nucleus X_n^m emits one alpha -particle and one beta -particle. What are the mass number and atomic number of the product nucleus?

An atom has mass number A and atomic number Z.How many protons are present in the nucleus ?

In the given radioactive disintegration series ._(92)^(235)U rarr_(82)^(207)Pb Calculate difference between number of alpha and number of beta particles emitted in this series.

An atom has mass number A and atomic number Z. How many neutrons are present in its nucleus ?

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.

Define the terms nucleus, nucleons, atomic number, mass number, isotopes, isobars, isotones.

One mole of alpha -particles are trapped inside a closed box. Find the number of electric field lines emanating from the alpha -particles.
