The statement "Electrons in the outermost shells react with other atoms" best explains how chemical reactions happen. Chemical reactions involve the interaction and sharing or transfer of electrons between atoms, particularly the electrons in the outermost energy levels (or valence shells) of the atoms. These outermost electrons are responsible for bonding and forming new molecules during a chemical reaction.
