Study Notes
- Quantum Mechanical Model of the Atom describes electron energies and positions
- Electronic structure of atoms involves main energy levels, sublevels, and orbitals
- Quantum numbers are used to describe electrons in an atom
- Essential questions include topics on microwave ovens, speed of light, wave properties, and color changes with temperature
- Atoms consist of dense nuclei and surrounding electrons, with chemical behavior related to electron arrangement
- Quantum theory involves quantized energy levels labeled by principal quantum number n
- Electrons occupy three-dimensional regions called orbitals, more likely closer to the nucleus
- Niels Bohr introduced the concept of definite energy levels and orbits around the nucleus
- When an electron transitions between orbits, photons are emitted corresponding to different series
- Photoelectric effect involves emission of electrons from a metal's surface when light shines on it
