CHMB41H3 Lecture Notes - Lecture 1: Louis De Broglie, Uncertainty Principle, Pauli Exclusion Principle
Document Summary
Organic compounds (derived from living organisms believed to contain immeasurable vital force) vs. inorganic compounds (derived from minerals lacking the vital force) Carbon neither readily gives up or accepts electrons; it shares. 1. 2: how the electrons in an atom are distributed. Louis de broglie showed electrons have wave like properties by combining einstein"s formula (relating mass and energy) with max planck"s formula (relating frequency and energy) ( 1924) Erwin schrodinger proposed the quantum mechanics model thought that electrons in an atom can be thought of as occupying a set of centric shells that surround the nucleus (- 1926) Aufbau"s principle: electron always goes into the available orbital with the lowest energy (closer to the nucleus = lower in energy) Pauli exclusion principle: no more than 2 electrons can occupy each atomic orbital and the electrons must be of opposite spins.
