Answer : The correct answer is ⁶⁴ Zn₃₀.The tomography is ⁰e₊₁ of the particles . When it is absorbed, the atomic number increases by 1, but the atomic mass remains the same . The given nuclide is ⁶⁴ Cu₂₉ . In this atomic mass is 64, and the atomic number 29 . So when you absorb a positron, the atomic number is increased by 1, which is the atomic number = 30 . Since the atomic number = 30 is for the Zinc atom , so that when ⁶⁴ Cu₂₉ absorb a positron occurs ⁶⁴ Zn ₃₀ as resulting atom . The reaction can be written as: ⁶⁴ Cu₂₉ + ⁰e₊₁ → ⁶⁴ Zn ₃₀
