Though your experiment is interesting, it is not necessarily true that the ball bounces half its previous height each time. Did you use a squash ball, then a football, a bowling ball, or a super ball ? you will find you get radically different results. And watch out for your fingers with that bowling ball.... No, you observed the loss of energy at each impact, energy being lost from the moving ball system and converted into heat in the surface of the table and in the material of the ball, not forgetting the sound energy (especially with that bowling ball) So, sadly no, there is no "magic number", and atoms don't follow the same rules at all. Things at that scale no longer follow what we would call common sense rules at all, and interactions become possibilities and likelihoods rather than certainties. Atoms don't "bounce" by falling under gravity, but wobble around at a rate proportional to their temperature. Steve
