Answer : The correct answer is ⁶⁴ Zn ₃₀ .
Positron is ⁰e₊₁ particle . When it is absorbed the atomic number increases by 1 but atomic mass remains same . The given nuclide is ⁶⁴ Cu₂₉ . In this atomic mass is 64 and atomic number is 29 .
So when it will absorb one positron the atomic number will increase by 1 that is atomic number = 30 . Since atomic number = 30 is for Zinc atom , so when ⁶⁴ Cu₂₉ absorb one positron it produces ⁶⁴ Zn ₃₀ as resulting atom . The reaction can be written as:
⁶⁴ Cu₂₉ + ⁰e₊₁ → ⁶⁴ Zn ₃₀
The resulting atom from a nuclide which absorbs a positron is ⁶⁴ Zn ₃₀ .
The atomic number of copper is 29
The atomic number of zinc is 30
In the reaction: the positron is ⁰e₊₁ particle. The mass number remains the same the moment it is absorbed when the atomic number increases ⁶⁴ Cu₂₉
So when it will absorb one positron the atomic number will increase by 1 that is atomic number = 30 .
Recall:
The atomic number of zinc is 30
so when ⁶⁴ Cu₂₉ absorb one positron it produces ⁶⁴ Zn ₃₀ as resulting atom .
The chemical reaction is given below:
⁶⁴ Cu₂₉ + ⁰e₊₁ → ⁶⁴ Zn ₃₀
