The correct answer is: **The number of protons in the atom changes.**
When an alpha particle (which consists of 2 protons and 2 neutrons, essentially a helium nucleus) is emitted from a nucleus, the original atom loses 2 protons and 2 neutrons. This change in the number of protons means that the element is transformed into a different element altogether, resulting in transmutation.
