The first controlled artificial disintegration of an atomic nucleus was achieved by

The isotope $_{92}U^{235}$ decays in a number of steps to an isotope of lead $_{82}Pb^{207}$. The groups of particles emitted in this process will be

An element $_{96}X^{227}$ emits $4\alpha$ and $5\beta$ particles to form a new element $Y$. The atomic number and mass number of $Y$ are:

$_{13}Al^{28}$ when radiated by a suitable projectile gives $_{15}P^{31}$ and a neutron. The projectile used is:

Which one of the following notations shows the product incorrectly?

$_{Z}X^{M} + _{2}He^{4} \to _{15}P^{30} + _{0}n^{1}$. Then
