Quantum Mechanics Terry A. Ring University of Utah

Movement of the Electron around the Nucleus

Erwin Rudolf Josef Alexander Schrödinger Born: 12 Aug 1887 in Erdberg, Vienna, Austria Died: 4 Jan 1961 in Vienna, Austria Nobel Prize in Physics 1933 "for the discovery of new productive forms of atomic theory"

Time Dependent Wave Equation!

Time Independent

Spherical Coordinates   r

Three Part Solution

Energy of the electron Energy is related to the Principle Quantum number, n. This gives 3 of the 4 quantum numbers, the last one is the spin quantum number, s, either +½ or – ½.

Wave Functions Probability to find an electron

Energy of the electron

Electron Transitions give off Energy as Light/Xrays E=hc/

Red/Blue Clouds in Space

Zeeman Effect Light Emission in Magnetic Field

Multi-electron Atoms (Wolfgang) Pauli Principle Exclusion Principle No 2 electrons with same quantum numbers!

Periodic Table of the Elements Dmitri Mendelyeev, 1869.

Light Emission from Elements Predicted

Shape of Molecules B2H6B2H6
