Lesson 5.1 – Beyond Bohr: Introduction to Quantum Mechanics
Bohr’s model was revolutionary, but it only worked for hydrogen-like atoms. The modern Quantum Mechanical Model replaces fixed orbits with probability clouds (orbitals).
Key Concepts:
- Schrödinger’s Wave Model: Electrons behave as waves.
- Orbitals (s, p, d, f): Electrons exist in probability regions rather than fixed paths.
- Heisenberg Uncertainty Principle: We cannot determine both position & momentum simultaneously.
