<b>Big Picture</b><br> <br> Name of theory:<br> <br> Real Answer:<br> <br> Why do we care about location of electrons?<br> a. <br> b. <br> <br> Classical Mechanics:<br> <br> <br> Quantum Mechanics:<br> <br> <br> <nowiki>DeBrolgie</nowiki>:<br> <br> <br> Bohr: ____________________ of electron = _________________ of electron.<br> <br> <Br> Planck:<br> <br> <br> Heisenberg Uncertainty Principle (1st "new" Quantum Mechanic theory we use):<br> <br> <br> <br> <br> <br> <b>So from Uncertainty Principle, we can know the Exact __________ of electron but never know<br> Exact _________ of electron. Therefore, we can only know the _____________________ of finding electron.</b><br> <br> <br> <br> 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!<br> <br> 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) <br> <br> <br> <br> <br> Therefore, ______________________ in 3-dimensional space is equal to a _____________________ . (for electron, it outside nucleus).<br> <br> <br> <b>Schrodinger: Did some math</b>, mathematically solved Bohr's concept: _______ of electron = __________ of electron<br> <br> <br> Called each answer/solution, ______________________ functions. Square of ______ function are _____________________.<br> <br> <br> Separated square of wave function (probability plots) into piles:<br> <Br> Energy Levels:<br> <br> <br> Why is Bohr happy?<br> <br> Subenergy levels:<br> <br> <br> Orbitals:<br> <br> <br> Defintion of orbitals:<br> <br> <br> Are there any regions outside nucleus electrons can't be? <br> <br> Nodes:<br> Number of nodes per energy level = _______________________________<br> <br> <br> <b>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.</b><br>
