Question Considering both sides of the equation representing a nuclear reaction, which is the same before and after the reaction?(1 point) Responses the total number of protons the total number of protons the energy the energy the types of atoms the types of atoms the number of alpha particles

Answer 1

In a nuclear reaction, the quantity that remains the same before and after the reaction is the total number of protons. This is due to the conservation of atomic number in nuclear reactions—while atoms may change into different elements, the total charge (which is the sum of the protons) is conserved.

So, the correct response is the total number of protons.
