Key Facts In This Video

  1. Physicists define "contact" between atoms or molecules as the moment when the attractive force balances out the repulsive force between them. 02:43

  2. The nuclear cores of different atoms and molecules do not naturally come together and "touch." 07:18

  3. Because electrons can't be defined as particles occupying a concrete space, analogies that involve them "touching" are problematic. 10:06
