30-2 Chapter 30 30.4. Set Up: has 7 protons, 7 neutrons and 7 electrons in the neutral atom. Table 30.2 gives the atomic mass to be 1 u is equivalent to 931.5 MeV. The mass defect is Solve: (a) (b) (c) 30.5. Set Up: The constituents of the neutral atom are one atom and one neutron. Table 30.2 gives the atomic mass to be The constituents of the neutral atom are two atoms and two neutrons. 1 u is equivalent to 931.5 MeV. The mass defect is Solve: (a) (b) (c) The binding energy per nucleon is much larger for than for Reflect: The masses in Table 30.2 are atomic masses and include the masses of the electrons that are present in the neutral atom. It is important to correctly account for the electron masses in the calculation. 30.6. Set Up: has 28 electrons and 56 nucleons, 28 protons and 28 neutrons. has 82 electrons and 207 nucleons, 82 protons and 125 neutrons. and 1 u is equivalent to 931.5 MeV. Solve: (a) and the binding energy is 492.3 MeV and the binding energy is 1629 MeV (b) binding energy per nucleon is binding energy per nucleon is (c) The binding energy is the energy needed to take the nucleus completely apart.

    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.
