← ScienceWhich consequence results when a transuranic element undergoes alpha decay?
A)Reduced atomic number, new element✓
B)Increased binding energy, stability
C)Neutron emission and chain reaction
D)Increased mass number, same element
💡 Explanation
Alpha decay releases helium nuclei, decreasing the atomic number by 2 therefore leading to a new element with altered properties. Transmutation occurs during radioactive decay, rather than altered mass or chain reactions typical of fission.
