One Practical Consequence: Leads to Description of All of Chemistry
Key Idea: Pauli Exclusion principle - each of the states predicted by the Schrodinger Equation can hold only two electrons
- Electrons have “spin”
- Each state hold one electron of spin up and one of spin down
Atoms - the entire periodic table is described by filling up the states adding one electron for each successive element
Molecules - from simple molecules like H2 to DNA and crystals - can be understood from these simple rules
