What exactly is transmutation?

http://en.wikipedia.org/wiki/Nuclear_transmutation

Transmutation is the process of changing one element into another by altering the number of protons in its nucleus. It was traditionally associated with alchemy, which aimed to transform common elements into precious ones, such as turning lead into gold. However, in modern scientific terms, transmutation is understood as nuclear transmutation, which occurs through nuclear reactions. These reactions involve bombarding a stable nucleus with high-energy particles, causing it to change into a different element.

To get a more detailed understanding of transmutation, you can refer to scientific textbooks or online resources that cover the topic of nuclear physics. These sources will explain the underlying principles, types of nuclear reactions, and the specific conditions required for transmutation to occur. Additionally, studying the historical development of alchemy can shed light on the early understanding and pursuit of transmutation.
