Chapter 5: Electrons in Atoms

5.1 Light and Quantized Energy
Wave nature of light, wavelength λ, frequency ν,
EMR ( electromagnetic radiation), amplitude, crest,
trough, electromagnetic spectrum, (speed of light) c = λ ν
Particle nature of light, quantum Equantum= h ν,
Planck’s constant h = 6.625 x 10-34 J, photoelectric effect, Ephoton = h ν,
Atomic emission spectra,

5.2 Quantum Theory and the Atom
Bohr model of the Atom, energy states of hydrogen, ground state,
hydrogen line spectrum, ΔE = Ehigher energy level – Elower energy level = Ephoton = h ν
The Quantum Mechanical Model of the Atom, electrons as waves, deBroglie, Heisenberg Uncertainty Principle, Schrodenger, orbital vs orbit, probability map, principal quantum numbers, principal energy levels (1-7), energy sublevels (s, p, d, f)

5.3 Electron Configurations
Ground state electron configurations, aufbau principle, Pauli Exclusion Principle ( ↑ ↓ ) , Hund’s rule, orbital diagrams and electron configuration notations, Valence electrons, Lewis, electron dot structure
