Question

Which quantity is the same before and after a nuclear change?(1 point) Responses atomic mass of each atom atomic mass of each atom atomic number of each atom atomic number of each atom total mass total mass total charge

Answer 1

In a nuclear change, the quantity that remains the same before and after the process is the **total charge**. While atomic mass, atomic number, and total mass may change in specific reactions (due to the conversion of mass to energy and the rearrangement of nucleons), the total charge is conserved.
