Study Notes
Quantum Mechanical Model of the Atom
- Formulated by Erwin Schrödinger, this model describes electrons in terms of probabilities, utilizing wave functions to incorporate quantum mechanics.
Existence of Atoms
- The concept of atoms was proposed by early Indian and Greek philosophers, notably by Democritus in ancient Greece, who suggested that matter is composed of indivisible particles.
Plum Pudding Model of the Atom
- Proposed by J.J. Thomson, this model described the atom as a uniform sphere of positively charged matter with negatively charged electrons embedded throughout, resembling a "plum pudding."
Gold Foil Experiment
- Conducted by Ernest Rutherford, this experiment involved directing alpha particles at a thin gold foil, leading to the discovery of the atomic nucleus and the realization that atoms are mostly empty space.
Quantized Energy and Photoelectric Effect
- Albert Einstein proposed the concept of quantized energy, explaining that light exists in discrete packets called photons, which explained the photoelectric effect and laid the groundwork for quantum theory.
