The energy required to separate a neutron and a proton from the nucleus is called:

Consider an $\alpha$-particle just in contact with a $_{92}U^{238}$ nucleus. Calculate the coulombic repulsion energy (i.e.,the height of the coulombic barrier between $U^{238}$ and $\alpha$-particle) assuming that the distance between them is equal to the sum of their radii.

In a nuclear fission chain reaction,a uranium atom undergoes fission to form two different products. The total mass of these products is:

When nuclear energy is intended to be harnessed for the generation of electricity,the potentially destructive neutrons released in a nuclear reactor are absorbed by:

$_{90}Th^{228}$ emits four alpha and one beta particles. The number of neutrons in the daughter element is:

In the decay,${}_Z^AX \to {}_{6}^{12}C + {}_{+1}^{0}\beta$,identify the values of $A$ and $Z$.
