“relate the quantum theory to the corresponding quantum number” what is your quantum number
Hence, 5.1 * 10^-11 alpha particles is being emitted each second by the sample.
<h3>What is half life?</h3>
The term half life is the time taken for only half of the original amount of radioactive nuclides to remain.
Thus, we have that the half life is 432.2 years or 1.36 * 10^10 s.
k = 0.693/ 1.36 * 10^10 s
k = 5.1 * 10^-11 alpha particles per second.
