$A$ photon of hard gamma radiation knocks a proton out of a $_{12}^{24}Mg$ nucleus to form:

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

Artificial elements have been prepared by bombardment reactions in high energy accelerators. What is the mass number of the element $X$ produced in the following nuclear reaction: $_{95}^{249}Cf + _{7}^{15}N \rightarrow _{105}X + 4_{0}^{1}n$?

Artificial radioactivity was first discovered by

Which of the following is a common use of a neutron in nuclear applications?

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
