Question 2

A radioactive isotope has a decay constant of $\lambda = 0.02 \text{ s}^{-1}$. Approximately how much time is required for $75\%$ of the sample to decay?

Question 3

In a nuclear reaction, if the total binding energy of the products is significantly less than the total binding energy of the reactants, what can be concluded about the reaction?

Question 4

Which of the following describes the process where an excited nucleus transfers its excess energy directly to an atomic electron, causing the electron to be ejected from the atom?

Question 5

The semi-empirical mass formula includes several terms to approximate the binding energy of a nucleus. Which term accounts for the tendency of nuclei to have an equal number of protons and neutrons for light stable nuclei?
