Name of theory:
Real Answer:
Why do we care about location of electrons?
a.
b.
Classical Mechanics:
Quantum Mechanics:
DeBrolgie:
Bohr: ____________________ of electron = _________________ of electron.
Planck:
Heisenberg Uncertainty Principle (1st "new" Quantum Mechanic theory we use):
So from Uncertainty Principle, we can know the Exact __________ of electron but never know
Exact _________ of electron. Therefore, we can only know the _____________________ of finding electron.
So how does Uncertainty Principle help in understanding where an electron is located in region of space outside of atom? Answer: Math and how we relate it to our physical world!
Example of Probability: Where your number of correct answer is on the Bell curve gives you the probability of how "well" you did on test compared to all other people (called Probability Plot)
Therefore, ______________________ in 3-dimensional space is equal to a _____________________ . (for electron, it outside nucleus).
Schrodinger: Did some math, mathematically solved Bohr's concept: _______ of electron = __________ of electron
Called each answer/solution, ______________________ functions. Square of ______ function are _____________________.
Separated square of wave function (probability plots) into piles:
Energy Levels:
Why is Bohr happy?
Subenergy levels:
Orbitals:
Defintion of orbitals:
Are there any regions outside nucleus electrons can't be?
Nodes:
Number of nodes per energy level = _______________________________
So add up all the area/volume of orbitals (you get subenergy), add up all area/volume of subenergy level (you get energy level), add up all area/volume of energy levels, you get the charged cloud.
