Document Summary
3. 3 the electron configurations and the periodic table. By the mid-1920s, it was clear that the bohr model of the atom could not be made to work. An entirely new model was needed and three physicists are credited with laying the foundations for this work, louis de broglie, werner heisenberg, and erwin. Their approach became known as wave mechanics or quantum mechanics and is still the most widely accepted model of the atom today. Quantum mechanics is a theory of atomic structure based on wave properties of elements. It is a theoretical branch of physics that deals with atomic and subatomic matter. To visualize a particle as a wave, it helps to consider that an electron"s location can only be specified as a statistical probability. The photons collide with the particle, changing both its location and speed). Basically, if you know where a particle is, you cannot know where it is going.
