03  Double Minima, Earnshaw's Theorem and PlumPuddings Organic Chemistry  Video

 과학
Continuing the discussion of Lewis structures and chemical forces from the previous lecture, Professor McBride introduces the doublewell potential of the ozone molecule and its structural equilibrium. The inability for inversesquare force laws to account for stable arrangements of charged particles is prescribed by Earnshaw's Theorem, which may be visualized by means of lines of force. J.J. Thomson circumvented Earnshaw's prohibition on structure by postulating a "plumpudding" atom. When Rutherford showed that the nucleus was a point, Thomson had to conclude that Coulomb's law was invalid at small distances.
