Question

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

Explanation:

Step1: Recall nuclear - reaction conservation laws

In nuclear reactions, the total number of protons (atomic number) and the total number of neutrons and protons (mass number) are conserved. The types of atoms can change due to processes like alpha - decay, beta - decay, etc. The number of alpha particles is not necessarily the same before and after the reaction. Energy is released or absorbed in nuclear reactions. But the total number of protons is conserved in a nuclear reaction.

Answer:

the total number of protons
