The daughter nuclide when Ni-78 undergoes beta decay - option D. Ni-78 as beta decay cause a change in atomic number only.
Beta decay is the radioactive decay that emits a beta particle from an atomic nucleus. This causes not just beta particle but some gamma radiation as well. It is represented by [tex]\beta ^{-}[/tex] and notation is ₋₁β⁰
- Daughter nucleus contains the same number of nucleons as the parent nucleus
- one of the neutrons changes into a proton
- As the proton number is increased by 1, the atomic number (Z) is increased by one
- Ni-78, 78 is atomic mass (neutron + proton), as mention above only atomic number change and number of nucleons remain same, which means atomic mass has no change.
Thus, the correct answer would be: option D. Ni-78 as beta decay cause a change in atomic number only.
