Copper can be converted into gold by

A. Artificial radioactivity
B. Heating
C. Electroplating
D. Chemical reaction
E. None of above

Check Answer

The correct answer is A) Artificial radioactivity.
Detailed Answer:
It is not possible to convert copper into gold through any known chemical or physical process. Copper and gold are distinct chemical elements that cannot be transformed into one another. Copper has an atomic number of 29 and an atomic weight of 63.54, while gold has an atomic number of 79 and an atomic weight of 196.966. These differences in their atomic structures mean that copper and gold have different chemical and physical properties, and it is not possible to change one element into the other through any known process.

In the past, alchemists attempted to transform base metals into gold through a process called transmutation, but these efforts were ultimately unsuccessful. While it is theoretically possible to transform one element into another through nuclear reactions, such as artificial radioactivity, these processes are complex and require specialized equipment and expertise that is not readily available.
