    What process can change a proton to a neutron, and vise versa?

    Isolated neutrons naturally decay into a proton and electron, with a half-life of ~15 min.
    A proton can decay into a neutron by emitting a positron ( known as beta+ decay), but this only occurs within the nuclei of certain isotopes of some elements. ( those scenarios where the nucleus is more stable with one less proton and one more neutron.)
