sir, there is no zym in my locality, can i take exercises at home
  1. Liquid-Drop Model . Nucleons are treated like molecules in a drop of liquid The nucleons interact strongly with one another They undergo frequent collisions as they jiggle around in the nucleus . The jiggling motion is analogous to the thermally agitated motion of molecules in a drop of liquid

  8. Fig. 11.14 A nucleon at the surface of a nucleus interacts with fewer other nucleons than one in the interior of the nucleus and hence its binding energy is less. The larger the nucleus the smaller the proportion of nucleons at the surface.
