30.8. Set Up: The wavelength of the photon is related to of the nuclear transition by Solve: 30.9. Set Up: In the nucleon number decreases by 4 and the atomic number decreases by 2. The atomic number of Po is 84. An is the nucleus of and the atomic mass of is 4.00260 u. 1 u is equivalent to 931.5 MeV. Solve: (a) The daughter nucleus is lead with and (b) The mass change is 84 electrons are included on each side of the decay equation so their masses cancel. The energy released is 6.12 MeV. This is the kinetic energy of the if recoil of the daughter nucleus is ignored. Reflect: For a radioactive decay to be energetically possible the mass of the products must be less than the mass of the parent. 30.10. Set Up: In beta decay an electron, is emitted by the nucleus. The beta decay reaction is If neutral atom masses are used, includes one electron and includes two electrons. One electron mass cancels and the other electron mass in represents the emitted electron. Or, we can subtract the electron masses and use the nuclear masses. The atomic mass of

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
