A Nuclide Of ${ }_{29}^{64} Cu$ Absorbs A Positron. Which Is The Resulting Atom?A. ${ }_{29}^{65} Cu$ B. \${ }_{29}^{63} Cu$[/tex\] C. ${ }_{28}^{64} Ni$ D. ${ }_{30}^{64} Zn$
In nuclear physics, a nuclide is a specific type of atom that is characterized by its atomic number (number of protons) and mass number (total number of protons and neutrons). The nuclide ${ }_{29}^{64} Cu$ represents a specific type of copper atom with 29 protons and 35 neutrons.
What is a Positron?
A positron is the antiparticle of an electron. It has the same mass as an electron but opposite charge. When a positron collides with an electron, they annihilate each other, releasing energy in the form of gamma rays.
The Effect of Positron Absorption on a Nuclide
When a positron is absorbed by a nuclide, it combines with a proton in the nucleus to form a neutron. This process is known as beta plus decay. The resulting atom will have the same mass number as the original nuclide but a different atomic number.
Applying the Concept to the Given Nuclide
Let's apply the concept of positron absorption to the given nuclide ${ }_{29}^{64} Cu$. When a positron is absorbed, it combines with a proton in the nucleus to form a neutron. This reduces the atomic number of the nuclide by 1, resulting in a new atom with 28 protons.
Determining the Resulting Atom
The resulting atom will have the same mass number as the original nuclide, which is 64. However, the atomic number will be reduced by 1, resulting in a new atom with 28 protons. This corresponds to the element nickel (Ni).
Conclusion
Based on the concept of positron absorption and beta plus decay, the resulting atom from the nuclide ${ }{29}^{64} Cu$ is ${ }{28}^{64} Ni$.
Answer
The correct answer is C. ${ }_{28}^{64} Ni$.
