Question
A nucleus with mass number A and atomic number Z
undergoes β⁻ decay. Which of the following is correct about the daughter nucleus?Solution
In β⁻ decay, a neutron inside the nucleus is converted into a proton, emitting a beta particle (electron) and an antineutrino. Since a neutron becomes a proton, the atomic number (Z) increases by 1, but the mass number (A) remains unchanged because both protons and neutrons contribute equally to it. So, after β⁻ decay:
- Z → Z + 1
- A remains the same
