Anuclide of mc012-1.jpg absorbs a positron. which is the resulting atom? mc012-2.jpg mc012-3.jpg mc012-4.jpg mc012-5.jpganswer is d

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

A chemical reaction simply refers to a process whereby one or more substances are converted to one or more different substances. In orders words, they are reactions in which reactants are concerted to produce products
