Calculate the neutron-proton ratios for the following nuclides, and determine where they lie in relation to the band of stability. \begin{equation}a. _{92}^{235} \mathrm{U}\end{equation} \begin{equation}b. _{8}^{16} \mathrm{O}\end{equation} \begin{equation}c. _{26}^{56} \mathrm{Fe}\end{equation} \begin{equation}c. _{60}^{156} \mathrm{Nd}\end{equation}
The parent nuclide of the thorium decay series is \(_{90}^{232}\) Th. The first four decays are as follows: alpha emission, beta emission, beta emission, and alpha emission. Write the nuclear equations for this series of emissions.
Explain how the strong force holds a nucleus together despite the repulsive forces between protons.
