According to Yukawa's meson theory of nuclear forces, the rapid exchange of which specific particles — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Meson theory postulates that the attractive forces between unlike nucleons (p and n) are caused by the oscillation of charged pi-mesons ($\pi^+$ or $\pi^-$), while forces between like nucleons (p-p or n-n) result from neutral mesons ($\pi^0$).
