    An α-particle is bombarded on 14N. As a result, a 17O nucleus is formed and a particle is emitted. This particle is a
    (a) neutron
    (b) proton
    (c) electron
    (d) positron.
    digAnsr:   b
    Ans : (b) proton
    If an alpha particle is bombarded on a nitrogen (N-14) nucleus, an oxygen (O-17) nucleus and a proton are released.
    According to the conservation of mass and charge,
    `` {}_{2}{}^{4}He+{}_{7}{}^{14}N\to {}_{6}{}^{17}O+{}_{1}{}^{1}p``
    So, the emitted particle is a proton.
