Which statement best describes the two reactions?AB
Explain why isotopes of the same element behave differently in nuclear reactions but not in chemical reactions.
Isotopes of the same element differ only in neutron numbers. Nuclear reactions involve changes to the protons or neutrons in an atom’s nucleus, but not changes to its electrons. Chemical reactions involve changes to the electrons in atoms, but not changes to its protons or neutrons. Isotope behavior only differs when a reaction involves neutrons.

Explain why isotopes of the same element behave differently in nuclear reactions but not in chemical reactions.
Isotopes of the same element have different numbers of neutrons, which can affect nuclear reactions. Chemical reactions involve electrons rather than the nucleus, and isotopes of the same element have the same electron arrangement.
