In gamma ray emission from a nucleus
only the proton number changes
both the neutron number and the proton number change
there is no change in the proton number and the neutron number
only the neutron number changes
As we learnt in
γ decay -
ray emitted when nucleus undergoes radio active decay left it in excited state
- wherein
After emission of particle the product nucleus formed in excited state
emission takes place due to deexcitation of the nucleus. Therefore during emission, there is no change in the proton and neutron number.
