What is a key difference between chemical and nuclear reactions? In chemical reactions, new compounds are formed. In nuclear reactions, compounds are destroyed. Chemical reactions involve electron rearrangements. Nuclear reactions involve changes to the nucleus. Chemical reactions involve large changes in energy. Nuclear reactions absorb or release small amounts of energy. In chemical reactions, only alpha radiation is emitted. In nuclear reactions, alpha, beta, and gamma decay may occur.
