ONLY USE THE FORMULAS GIVEN ON PAPER, NO OTHER FORMULAS ALLOWED. DOUBLE CHECK ANSWERS FOR ANY MISTAKES! 5. (a) We have a collection of Hydrogen atoms in the ground state. They are bombarded with photons of energy 12.1 MeV. What are the energies of the photons that can be emitted by the excited Hydrogen atoms? b. Why do the more stable high A elements generally have more neutrons than protons? Possibly (but not necessarily) useful formulae and constants 5 53...
