    A certain hypothetical atom contains 68 protons and 87 neutrons in its nucleus and has an atomic mass of 154.2 atomic mass units, or amu (an amu is approximately 1.66 * 10^-27 kg). How many protons and how many neutrons will it end up with if it undergoes an alpha decay? How many if it undergoes a beta decay? How many if it undergoes a gamma decay?

    In alpha decay the nucleus emits an alpha particle (nucleus of helium atom with two protons and two neutrons) resulting in a new nucleus with two protons less and two neutrons less (i.e. atomic number less ...

    Solution Summary

    This solution shows how to find the number of protons and neutrons an atom will contain if it undergoes an alpha decay, a beta decay, and a gamma decay, respectively.
