As stated above, the planetary model showed that atoms, instead of being hard, indestructible and indivisible particles, consisted of vast regions of empty space, in which extremely small particles - electrons - moved around the nucleus, bound to it by electromagnetic forces. But, later development in Quantum physics established that even these particles were not solid objects of classical physics. They appear sometimes as particles, and sometimes as waves.
