This is a challenging multi-step problem. Solve it on paper, writing out each step carefully. When doing calculations, do not round intermediate values. Note: If you have approached the problem in a principled way, do not abandon your approach if your numerical answer is not accepted; check your calculations! The Bohr model correctly predicts the main energy levels not only for atomic hydrogen but also for other "one-electron" atoms where all but one of the atomic electrons has been removed,...

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...

Some early theories on nuclear structure proposed that the nucleus contained a number of electrons. Suppose that this is true. Treat an electron in the nucleus as a 1-dimensional Particle in a Box that has a nuclear size. In other words, the width of the box is 3 x 10-14 m. What is the Energy of the Ground State (give your answer in MeV)? Tries 0/3 What is the Energy of the First Excited State (give your answer in MeV)?...
