Tuesday 24 October
- P2
wash desks
- Show
tests scores (hand back papers)
- Classical Theory of Atom
- nucleus
- has most of the mass
- protons and neutrons
- electrons
- problems:
- ultraviolet catastrophe
- p. 93, p. 94
- Planck
- energy comes in little
packets called quanta
- frequency determines
energy
- E = hn
- E = energy
- h = Planck's constant
- each frequency has a
minimum amount of E needed to exist
- photoelectric effect
- pp. 93-94
- Einstein
- light comes in little
packets called photons
- frequency determines E
- high n gives high E
- low n gives low E
- atomic emission-line
spectra
- pp.94-95
- Bohr
- e- exist in
exact orbitals
- e- cannot
exist between orbitals
- atoms should not exist
(should collapse)
- pp. 96-97
- e- in an
orbital does not move
- quantum mechanics
- Atomic
Bingo
- homework
- Tuesday 31 October Chapter

101-104
- Principal (Quantum Number)
- n
- E level occupied by an e-
- indicates main energy
level of an orbital
- positive integers: 1, 2,
