How molecules feel and the world they live in

DNA, RNA: C,H,N,O,P, [Mg++] Carbs: C,H,O Protein: C,H,N,O, (S),(P) [traces] Membranes: C,H,N,O,P, (S) What cannot be done with connections of these atoms cannot be done by living organisms.

At the start: the number of protons (positively charged particles) equal the number of electrons (negatively charged particles) Atoms seek complete outer shells. Meaning the outermost electron set should be 8. (Hydrogen and Helium only want 2).
