Study Notes
Quantum Chemistry Test Review
-
Spectral Line Series for Hydrogen
- Lyman series: Goes from a higher energy level to the 1st energy level (n1), emitting UV radiation.
- Balmer series: Goes from a higher energy level to the 2nd energy level (n2), emitting visible light.
- Paschen series: Goes from a higher energy level to the 3rd energy level (n3), emitting IR radiation.
Electromagnetic Radiation
-
Electromagnetic Spectrum
- Radio waves: Longest wavelength.
- Gamma rays: Shortest wavelength.
- Visible light spectrum: Red has the longest and violet has the shortest wavelength.
Spectroscopy
- Continuous Spectrum: All colors of the rainbow are present.
- Emission Spectrum: specific wavelengths of light are emitted.
- Absorption Spectrum: Dark lines appear on a continuous spectrum due to absorbed specific wavelengths of light.
Electron Configuration Rules
- Aufbau Principle: Electrons first occupy the lowest energy levels.
- Pauli Exclusion Principle: An orbital can hold a maximum of two electrons with opposite spins.
- Hund's Rule: Electrons spread out over orbitals to maximize their number with parallel spins before pairing up.
Electron Configuration
