Shrodinger+A3



THEORY: Schrodinger believed electrons were waves. Shrodinger used math equations called wave functions to make probable predictions on the chracteristics of electrons. He explained there was an uncertainty factor in trying to find where the electrons were. However Schrodinger's model was not necessarily a physical one. He used his wave equation to determine the probable properties in the characteristics of an electron, not the physical appearance.

NEW DISCOVERY AND UNDERSTANDING ADDED TO PAST MODELS :He enhanced Bohr's model and added to the electron cloud model by allowing it to become 3D by using three quantum numbers which are: the principal (//n//), angular (//l//), and magnetic (//m//). Shrodinger's atomic theory of 1930 developed the wave mechanics. He contributed to the electron cloud model by combing de Broglie's theory with the use of waves. These both were used to determine the distribution of electrons in the atom and about explaining the movement of an electron in an atom as a wave. The de Broglie equation to Schrodinger was too simple for him. Schrodinger didn't like combining particles and waves, so he stuck to waves. His equation was like equations for sound waves and electromagnetic waves. It was very important in the contributions to learning about the atom. In Schrodinger’s wave equation there is an unknown material of the atom, called the wave function which is symbolized by the Greek letter (psi). (Similiar to a fork or Neptune's trident) When used on the hydrogen atom, Schrodinger’s wave equation had all the results of Bohr and de Broglie.

ONE PROBLEM: These mechanics can't tell the motion, position or velocity at anytime. It just tells how the wave function evolves in space and time. In other word's, it predicts some properties it might have. This model no longer tells us where the electron is; it only tells us where it might be. Schrodinger's model also does not show the particle properties of the electron. It would be hard to protray electrons as waves. Now, scientists use the Atomic Orbital Model which shows the electrons precise characteristics.
