* Chemical reactions involve electrons: Chemical reactions occur when atoms share, gain, or lose electrons. These interactions happen in the electron shells surrounding the nucleus, not within the nucleus itself.
* Nucleus contains protons and neutrons: The nucleus contains protons and neutrons, which are bound together by strong nuclear forces. These forces are much stronger than the forces involved in chemical reactions.
* Nuclear reactions involve the nucleus: Reactions that involve changes to the nucleus, such as nuclear fission or fusion, are called nuclear reactions and are distinct from chemical reactions.
In summary: The nucleus provides the overall structure and identity of an atom, but its role in chemical reactions is indirect. The electrons, which are located outside the nucleus, are the primary participants in chemical bonding and reactions.
