Reviewed History of the Atom - note sheet
Discussed Bohr model and present day model of atom.
Bohr - had electrons in fixed orbit
Quantum mechanical model - probability of finding an electron in an orbital.
Gave topics for quiz on Friday:
models of the atom
parts of the atom
average atomic mass
Ion (different # electrons)vs. Atom (different # protons) vs Isotope (different # neutrons)
Isotope notation
Average Atomic Mass Calculations
Gave handouts: History of the Atom, Review Sheet - Atom and Atom History paragraph.
electromagnetic spectrum (color of light / wavelength / energy)
orbitals (degenerate)
energy of a photon (2X)
quantum numbers
photoelectric effect (2x)
Bohr model electron movement (2x)
deBroglie wavelength (2x)
Heisenberg uncertainty principle
