Midterm 2 Memorization Flashcards
the fact that we cannot simultaneously measure the exact position and precise momentum of an electron is
Heisenberg uncertainty principle
“one places electrons into orbitals one by one from low energy to high energy”
ex: fill 1s orb then 2s, then 2p, etc
Aufbau Principle
the principle that is based on electrons attempting to be as far apart as possible
ex: must put spin up arrows in each orbital before adding the spin down arrows
Hund’s rule
wave-particle duality. wavelength and momentum are associated
De’Broigle
no two electrons in the same atom can have identical values for all 4 of the quantum numbers.
(no more than two electrons can occupy the same orbital and one must be spin up while other is spin down).
