|Of course the nuclei of the atoms in the body are held together by
nuclear forces. Under all normal circumstances these nuclei undergo no
changes, so those forces play no active role in body processes. that
leaves just gravity and, of course, the main force involved in all
sorts of chemical and mechanical processes- electromagnetism. |
I don't know any special tricks for understanding chemistry. Medical students do a lot of memorizing.
