Answer:

Chemical reactions involve the loss, gain, or sharing of electrons, but do not involve changes to the nucleus of an atom. Nuclear reactions involve changes to the nucleus and produce a new particle. Chemical reactions involve low energy changes. Chemical reactions never involve a change in the mass of atoms.
